XFS is optimized for large file transfers and parallel I/O operations, while ext4 is optimized for general-purpose use with a focus on security. backups ). Regarding filesystems. Small_Light_9964 • 1 yr. Which file system would you consider the best for my needs and what should I be aware of when considering the filesystem you recommend? Please add your thoughts and comment below. Proxmox running ZFS. Austria/Graz. com The Proxmox VE installer, which partitions the local disk (s) with ext4, XFS, BTRFS (technology preview), or ZFS and installs the operating system. I've used BTRFS successfully on a single drive proxmox host + VM. This is not ZFS. ext4 4 threads: 74 MiB/sec. Issue the following commands from the shell (Choose the node > shell): # lvremove /dev/pve/data # lvresize -l +100%FREE /dev/pve/root #. In the preceding screenshot, we selected zfs (RAID1) for mirroring, and the two drives, Harddisk 0 and Harddisk 1, to install Proxmox. There is no need for manually compile ZFS modules - all packages are included. When you do so Proxmox will remove all separately stored data and puts your VM's disk back. ISO's could probably be stored on SSD as they are relatively small. Create a VM inside proxmox, use Qcow2 as the VM HDD. This. Note 2: The easiest way to mount a USB HDD on the PVE host is to have it formatted beforehand, we can use any existing Linux (Ubuntu/Debian/CentOS etc. Features of the XFS and ZFS. Happy server building!In an other hand if i install proxmox backup server on ext4 inside a VM hosted directly on ZFS of proxmox VE i can use snapshot of the whole proxmox backup server or even zfs replication for maintenance purpose. To me it looks it is worth to try conversion of EXT4 to XFS and obviously need to either have full backup or snapshots in case of virtual machines or even azure linux vms especially you can take os disk snapshot. Here is a look at the Linux 5. Subscription Agreements. /dev/sdb ) from the Disk drop-down box, and then select the filesystem (e. Festplattenkonfiguration -//- zfs-RAID0 -//- EXT4. Hello, this day have seen that compression is default on (rpool) lz4 by new installations. Sure the snapshot creation and rollback ist faster with btrfs but with ext4 on lvm you have a faster filesystem. They perform differently for some specific workloads like creating or deleting tenthousands of files / folders. ext4 is slow. A execução do comando quotacheck em um sistema de. proxmox-boot-tool format /dev/sdb2 --force - change mine /dev/sdb2 to your new EFI drive's partition. 0 is in the pre-release stage now and includes TRIM,) and I don't see you writing enough data to it in that time to trash the drive. btrfs for this feature. 2. 2. Select the local-lvm, Click on “Remove” button. I created the zfs volume for the docker lxc, formatted it (tried both ext4 and xfs) and them mounted to a directory setting permissions on files and directories. Additionally, ZFS works really well with different sized disks and pool expansion from what I've read. In doing so I’m rebuilding the entire box. With Discard set and a TRIM-enabled guest OS [29], when the VM’s filesystem marks blocks as unused after deleting files, the controller will relay this information to the storage, which. Earlier this month I delivered some EXT4 vs. Starting new omv 6 server. What's the right way to do this in Proxmox (maybe zfs subvolumes)?8. Proxmox VE Linux kernel with KVM and LXC support. Step 5. Você deve ativar as cotas na montagem inicial. If I were doing that today, I would do a bake-off of OverlayFS vs. Best Linux Filesystem for Ethereum Node: EXT4 vs XFX vs BTRFS vs ZFS. Ext4 ist dafür aber der Klassiker der fast überall als Standard verwendet wird und damit auch mit so ziemlich allem läuft und bestens getestet ist. 7. I think. This results in the clear conclusion that for this data zstd. Everything on the ZFS volume freely shares space, so for example you don't need to statically decide how much space Proxmox's root FS requires, it can grow or shrink as needed. Step 7. Below is a very short guide detailing how to remove the local-lvm area while using XFS. shared storage, etc. 1) using an additional single 50GB drive per node formatted as ext4. Based on the output of iostat, we can see your disk struggling with sync/flush requests. This can be an advantage if you know and want to build everything from scratch, or not. Ext4 focuses on providing a reliable and stable file system with good performance. XFS provides a more efficient data organization system with higher performance capabilities but less reliability than ZFS, which offers improved accessibility as well as greater levels of data integrity. [root@redhat-sysadmin ~]# lvextend -l +100%FREE /dev/centos/root. Maybe a further logical volume dedicated to ISO storage or guest backups?ZFS doesn't really need a whole lot of RAM, it just wants it for caching. As the load increased, both of the filesystems were limited by the throughput of the underlying hardware, but XFS still maintained its lead. Replication uses snapshots to minimize traffic sent over. I chose two established journaling filesystems EXT4 and XFS two modern Copy on write systems that also feature inline compression ZFS and BTRFS and as a relative benchmark for the achievable compression SquashFS with LZMA. want to run insecure privileged LXCs you would need to bind-mount that SMB share anyway and by directly bind-mounting a ext4/xfs formated thin LV you skip that SMB overhead. Still, I am exclusively use XFS where there is no diverse media under the system (SATA/SAS only, or SSD only), and had no real problem for decades, since it's simple and it's fast. ZFS dedup needs a lot of memory. Enter the username as root@pam, the root user’s password, then enter the datastore name that we created earlier. 2010’s Red Hat Enterprise Linux 6. LVM supports copy-on-write snapshots and such which can be used in lieu of the qcow2 features. ZFS is faster than ext4, and is a great filesystem candidate for boot partitions! I would go with ZFS, and not look back. EXT4 is still getting quite critical fixes as it follows from commits at kernel. ZFS storage uses ZFS volumes which can be thin provisioned. Something like ext4 or xfs will generally allocate new blocks less often because they are willing to overwrite a file or post of a file in place. x or newer). With classic filesystems, the data of every file has fixed places spread across the disk. However the default filesystem suggested by the Centos7 installer is XFS. I. Si su aplicación falla con números de inodo grandes, monte el sistema de archivos XFS con la opción -o inode32 para imponer números de inodo inferiores a 232. Proxmox installed, using ZFS on your NVME. For example it's xfsdump/xfsrestore for xfs, dump/restore for ext2/3/4. Exfat compatibility is excellent (read and write) with Apple AND Microsoft AND Linux. The root volume (proxmox/debian OS) requires very little space and will be formatted ext4. fiveangle. 3. Clean installs of Ubuntu 19. Then I was thinking about: 1. I use lvm snapshots only for the root partition (/var, /home and /boot are on a different partitions) and I have a pacman hook that does a snapshot when doing an upgrade, install or when removing packages (it takes about 2 seconds). As cotas XFS não são uma opção remountable. But default file system is ext4 and I want xfs file system because of performance. How to convert existing filesystem from XFS to Ext4 or Ext4 to XFS? Solution Verified - Updated 2023-02-22T15:39:33+00:00 - Englishto edit the disk. # xfs_growfs -d /dev/sda1. Con: rumor has it that it is slower than ext3, the fsync dataloss soap. 5 Gbps, Proxmox will max out at 1. I try to install Ubuntu Server and when the installation process is running, usually in last step or choose disk installation, it cause the Proxmox host frozen. You're better off using a regular SAS controller and then letting ZFS do RAIDZ (aka RAID5). . So I think you should have no strong preference, except to consider what you are familiar with and what is best documented. Snapshots, transparent compression and quite importantly blocklevel checksums. But I think you should use directory for anything other than normal filesystem like ext4. 10 is relying upon various back-ports from ZFS On Linux 0. See this. backups ). I don't know anything about XFS (I thought unRaid was entirely btrfs before this thread) ZFS is pretty reliable and very mature. No idea about the esxi VMs, but when you run the Proxmox installer you can select ZFS RAID 0 as the format for the boot drive. I get many times a month: [11127866. Hello, I've migrated my old proxmox server to a new system running on 4. RAID. For a single disk, both are good options. XFS was surely a slow-FS on metadata operations, but it has been fixed recently as well. ZFS: Full Comparison. There are a lot of post and blogs warning about extreme wear on SSD on Proxmox when using ZFS. However, to be honest, it’s not the best Linux file system comparing to other Linux file systems. Ext4 is the default file system on most Linux distributions for a reason. Elegir un sistema de archivos local 1. 4 HDD RAID performance per his request with Btrfs, EXT4, and XFS while using consumer HDDs and an AMD Ryzen APU setup that could work out for a NAS type low-power system for anyone else that may be interested. for that you would need a mirror). This allows the system administrator to fine tune via the mode option between consistency of the backups and downtime of the guest system. • 2 yr. Click remove and confirm. El sistema de archivos XFS. XFS has a few features that ext4 has not like CoW but it can't be shrinked while ext4 can. Dropping performance in case with 4 threads for ext4 is a signal that there still are contention issues. Compared to classic RAID1, modern FS have two other advantages: - RAID1 is whole device. If this were ext4, resizing the volumes would have solved the problem. Fstrim is show something useful with ext4, like X GB was trimmed . Using Btrfs, just expanding a zip file and trying to immediately enter that new expanded folder in Nautilus, I am presented with a “busy” spinning graphic as Nautilus is preparing to display the new folder contents. 6. The one they your distribution recommends. Each to its own strengths. Given that, EXT4 is the best fit for SOHO (Small Office/Home. El sistema de archivos es mayor de 2 TiB con inodos de 512 bytes. I figured my choices were to either manually balance the drive usage (1 Gold for direct storage/backup of the M. If you use Debian, Ubuntu, or Fedora Workstation, the installer defaults to ext4. Both Btrfs and ZFS offer built-in RAID support, but their implementations differ. using ESXi and Proxmox hypervisors on identical hardware, same VM parameters and the same guest OS – Linux Ubuntu 20. GitHub. Created new nvme-backed and sata-backed virtual disks, made sure discard=on and ssd=1 for both in disk settings on Proxmox. Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. It is the default file system in Red Hat Enterprise Linux 7. 1. A catch 22?. By default, Proxmox will leave lots of room on the boot disk for VM storage. In the directory option input the directory we created and select VZDump backup file: Finally schedule backups by going to Datacenter – > Backups. You need to confirm the filesystem type you're using, Red Hat uses the XFS filesystem, but you can check the filesystem with lsblk -f or df -Th. The EXT4 f ile system is 48-bit with a maximum file size of 1 exbibyte, depending on the host operating system. All have pros and cons. So that's what most Linux users would be familiar with. The ID should be the name you can easily identify the store, we use the same name as the name of the directory itself. ZFS is supported by Proxmox itself. I have a 1TB ssd as the system drive, which is automatically turned into 1TB LVM, so I can create VMs on it without issue, I also have some HDDs that I want to turn into data drives for the VMs, here comes to my puzzle, should I. So far EXT4 is at the top of our list because it is more mature than others. Set. Testing. This is why XFS might be a great candidate for an SSD. Note: If you have used xfs, replace ext4 with xfs. ZFS combines a file system and volume manager, offering advanced features like data integrity checks, snapshots, and built-in RAID support. Which well and it's all not able to correct any issues, Will up front be able to know if a file has been corrupted. BTRFS integration is currently a technology preview in Proxmox VE. The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well. After a week of testing Btrfs on my laptop, I can conclude that there is a noticeable performance penalty vs Ext4 or XFS. or really quite arbitrary data. I have a high end consumer unit (i9-13900K, 64GB DDR5 RAM, 4TB WD SN850X NVMe), I know it total overkill but I want something that can resync quickly new clients since I like to tinker. The EXT4 f ile system is 48-bit with a maximum file size of 1 exbibyte, depending on the host operating system. BTRFS is a modern copy on write file system natively supported by the Linux kernel, implementing features such as snapshots, built-in RAID and self healing via checksums for data and metadata. NVMe drives formatted to 4096k. 1. B. Você deve ativar as cotas na montagem inicial. 2 NVMe SSD (1TB Samsung 970 Evo Plus). Regardless of your choice of volume manager, you can always use both LVM and ZFS to manage your data across disks and servers when you move onto a VPS platform as well. This is a major difference because ZFS organizes and manages your data comprehensively. aaron said: If you want your VMs to survive the failure of a disk you need some kind of RAID. The hardware raid controller will and does function the same regardless if the file system is NTFS, ext(x), xfs, etc etc. Pro: supported by all distro's, commercial and not, and based on ext3, so it's widely tested, stable and proven. Prior using of the command EFI partition should be the second one as stated before (therefore in my case sdb2). As cotas XFS não são uma opção remountable. . The following command creates an ext4 filesystem and passes the --add-datastore parameter, in order to automatically create a datastore on the disk. Copied! # xfs_growfs file-system -D new-size. Proxmox can do ZFS and EXT4 natively. Dependending on the hardware, ext4 will generally have a bit better performance. New features and capabilities in Proxmox Backup Server 2. Redundancy cannot be achieved by one huge disk drive plugged into your project. But now, we can extend lvm partition on the fly without live cd or reboot the system, by resize lvm size only. with LVM and ext4 some time ago. A 3TB / volume and the software in /opt routinely chews up disk space. Also, with lvm you can have snapshots even with ext4. In the vast realm of virtualization, Proxmox VE stands out as a robust, open-source solution that many IT professionals and hobbyists alike have come to rely on. What you get in return is a very high level of data consistency and advanced features. Starting from version 4. Feature-for-feature, it doesn't use significantly more RAM than ext4 or NTFS or anything else does. Step 4: Resize / partition to fill all space. If only a single drive in a cache pool i tend to use xfs as btrfs is ungodly slow in terms of performance by comparison. Select Datacenter, Storage, then Add. Exfat is especially recommended for usb sticks and micro/mini SD cards for any device using memory cards. 5" SAS HDDs. by default, Proxmox only allows zvols to be used with VMs, not LXCs. Buy now!I've run zfs on all different brands of SSD and NVMe drives and never had an issue with premature lifetime or rapid aging. Comparing direct XFS/ext4 vs Longhorn which has distributed built-in its design, may provide the incorrect expectation. service. Yeah reflink support only became a thing as of v10 prior to that there was no linux repo support. When dealing with multi-disk configurations and RAID, the ZFS file-system on Linux can begin to outperform EXT4 at least in some configurations. For example, if a BTRFS file system is mounted at /mnt/data2 and its pve-storage. b) Proxmox is better than FreeNAS for virtualization due to the use of KVM, which seems to be much more. RAW or QCOW2 - The QCOW2 gives you better manageability, however it has to be stored on standard filesystem. The client uses the following format to specify a datastore repository on the backup server (where username is specified in the form of user @ realm ): [ [username@]server [:port]:]datastore. A execução do comando quotacheck em um sistema de. Use XFS as Filesystem at VM. I need to shrink a Proxmox-KVM raw volume with LVM and XFS. As putting zfs inside zfs is not correct. XFS and ext4 aren't that different. LVM, ZFS, and. But unless you intend to use these features, and know how to use them, they are useless. mount somewhere. + Access to Enterprise Repository. 7. Proxmox has the ability to automatically do zfs send and receive on nodes. Two commands are needed to perform this task : # growpart /dev/sda 1. I have a RHEL7 box at work with a completely misconfigured partition scheme with XFS. For LXC, Proxmox uses ZFS subvols, but ZFS subvols cannot be formatted with a different filesystem. Good day all. Get your own in 60 seconds. sdb is Proxmox and the rest are in a raidz zpool named Asgard. In doing so I’m rebuilding the entire box. This is why XFS might be a great candidate for an SSD. Get your own in 60 seconds. . we use high end intel ssd for journal [. Snapshot and checksum capability are useful to me. B. Head over to the Proxmox download page and grab yourself the Proxmox VE 6. Select local-lvm. I like having a separate cache array on NVME drives (BTRFS) for fast access to my dockers. Compared to ext4, XFS has unlimited inode allocation, advanced allocation hinting (if you need it) and, in recent version, reflink support (but they need to be explicitly enabled in. Btrfs is still developmental and has some deficiencies that need to be worked out - but have made a fair amount of progress. If you make changes and decide they were a bad idea, you can rollback your snapshot. 527660] XFS: loop5(22218) possible memory allocation deadlock size 44960 in kmem_alloc (mode:0x2400240) As soon as I get. by default, Proxmox only allows zvols to be used with VMs, not LXCs. In the future, Linux distributions will gradually shift towards BtrFS. fdisk /dev/sdx. 2. comments sorted by Best Top New Controversial Q&A Add a Comment [deleted] • Additional comment actions. 1, the installer creates a standard logical volume called “data”, which is mounted at /var/lib/vz. Now, the storage entries are merely tracking things. Ext4 has a more robust fsck and runs faster on low-powered systems. Each Proxmox VE server needs a subscription with the right CPU-socket count. EXT4 - I know nothing about this file system. Meaning you can get high availability VMs without ceph or any other cluster storage system. ext4 with m=0 ext4 with m=0 and T=largefile4 xfs with crc=0 mounted them with: defaults,noatime defaults,noatime,discard defaults,noatime results show really no difference between first two, while plotting 4 at a time: time is around 8-9 hours. If you have SMR drives, don't use ZFS! And perhaps also not BTRFS, I had a small server which unknown to me had an SMR disk with ZFS proxmox server to experiment with. ZFS, the Zettabyte file system, was developed as part of the Solaris operating system created by Sun Microsystems. cfg. Unfortunately you will probably lose a few files in both cases. Hello in a few threads it has been mentioned that in most cases using ext4 is faster and just as stable as xfs . You can check in Proxmox/Your node/Disks. Watching LearnLinuxTV's Proxmox course, he mentions that ZFS offers more features and better performance as the host OS filesystem, but also uses a lot of RAM. Ext4 파일 시스템. Journaling ensures file system integrity after system crashes (for example, due to power outages) by keeping a record of file system. You can create an ext4 or xfs filesystem on a disk using fs create, or by navigating to Administration -> Storage/Disks -> Directory in the web interface and creating one from there. I've never had an issue with either, and currently run btrfs + luks. How do the major file systems supported by Linux differ from each other?If you will need to resize any xfs FS to a smaller size, you can do it on xfs. It's not the fastest but not exactly a slouch. Additionally, ZFS works really well with different sized disks and pool expansion from what I've read. To be honest I'm a little surprised how well Ext4 compared with exFAT ^_^. Click to expand. If at all possible please link to your source of this information. El sistema de archivos XFS 1. 3 and following this guide to install it on a Hetzner server with ZFS Encryption enabled. Yeah those are all fine, but for a single disk i would rather suggest BTRFS because it's one of the only FS that you can extend to other drives later without having to move all the data away and reformat. There are plenty of benefits for choosing XFS as a file system: XFS works extremely well with large files; XFS is known for its robustness and speed; XFS is particularly proficient at parallel input/output (I/O. Web based management interfaceThe ext4 file system records information about when a file was last accessed and there is a cost associated with recording it. EXT4 is still getting quite critical fixes as it follows from commits at kernel. ext4 can claim historical stability, while the consumer advantage of btrfs is snapshots (the ease of subvolumes is nice too, rather than having to partition). This feature allows for increased capacity and reliability. In case somebody is looking do the same as I was, here is the solution: Before start, make sure login to PVE web gui, delete local-lvm from Datacenter -> Storage. If you installed Proxmox on a single disk with ZFS on root, then you just have a pool with single, single-disk vdev. # systemctl start pmcd. It has zero protection against bit rot (either detection or correction). jinjer Active Member. root@proxmox-ve:~# mkfs. One of the main reasons the XFS file system is used is for its support of large chunks of data. Things like snapshots, copy-on-write, checksums and more. An ext4 or xfs filesystem can be created on a disk using the fs create subcommand. We tried, in proxmox, EXT4, ZFS, XFS, RAW & QCOW2 combinations. Because of this, and because EXT4 seems to have better TRIM support, my habit is to make SSD boot/root drives EXT4, and non-root bulk data spinning-rust drives/arrays XFS. Still, I am exclusively use XFS where there is no diverse media under the system (SATA/SAS only, or SSD only), and had no real problem for decades, since it's simple and it's fast. Move/Migrate from 1 to 3. Outside of that discussion the question is about specifically the recovery speed of running fsck / xfs_repair against any volume formatted in xfs vs ext4, the backup part isnt really relevent back in the ext3 days on multi TB volumes u’d be running fsck for days!Now you can create an ext4 or xfs filesystem on the unused disk by navigating to Storage/Disks -> Directory. Requierement: 1. ZFS needs to lookup 1 random sector per dedup block written, so with "only" 40 kIOP/s on the SSD, you limit the effective write speed to roughly 100 MB/s. Select your Country, Time zone and Keyboard LayoutHi, on a fresh install of Proxmox with BTRFS, I noticed that the containers install by default with a loop device formatted as ext4, instead of using a BTRFS subvolume, even when the disk is configured using the BTRFS storage backend. I am setting up a homelab using Proxmox VE. Storages which present block devices (LVM, ZFS, Ceph) will require the raw disk image format, whereas files based storages (Ext4, NFS, CIFS, GlusterFS) will let you to choose either the raw disk image format or the QEMU image format. 6. Press Enter to Install Proxmox VE 7. 1 Login to Proxmox web gui. Things like snapshots, copy-on-write, checksums and more. yes, even after serial crashing. Sistemas de archivos en red 27. But for spinning rust storage for data. Quota journaling: This avoids the need for lengthy quota consistency checks after a crash. Although swap on the SD Card isn't ideal, putting more ram in the system is far more efficient than chasing faster OS/boot drives. The default, to which both xfs and ext4 map, is to set the GUID for Linux data. The way I have gone about this (following the wiki) is summarized by the following: First i went to the VM page via the proxmox web browser control panel. Buy now!The XFS File System. BTRFS and ZFS are metadata vs. Let’s go through the different features of the two filesystems. Utilice. Don't worry about errors or failure, I use a backup to an external hard drive daily. 0 einzurichten. . Funny you mention the lack of planning. I find the VM management on Proxmox to be much better than Unraid. RAID stands for Redundant Array of Independent Disks. Through many years of development, it is one of the most stable file systems. Install Proxmox to a dedicated OS disk only (120 gb ssd. This is the same GUID regardless of the filesystem type, which makes sense since the GUID is supposed to indicate what is stored on the partition (e. 对应的io利用率 xfs 明显比ext4低,但是cpu 比较高 如果qps tps 在5000以下 etf4 和xfs系统无明显差异。. I'd like to use BTRFS directly, instead of using a loop. While the XFS file system is mounted, use the xfs_growfs utility to increase its size: Copy. But running zfs on raid shouldn't lead to anymore data loss than using something like ext4. Set your Proxmox zfs mount options accordingly (via chroot) reboot and hope it comes up. 2 ensure data is reliably backed up and. . ext4 is a filesystem - no volume management capabilities. Snapshots are free. Without knowing how exactly you set it up it is hard to judge. If this works your good to go. It has zero protection against bit rot (either detection or correction). Hi, xfs und ext4 sind beides gute Datei-Systeme! Aber beide machen aus einem raid1 mit 4TB-Sata-Platten kein Turbo. storage pool type: lvmthin LVM normally allocates blocks when you create a volume. Be sure to have a working backup before trying filesystem conversion. xfs but I don't know where the linux block device is stored, It isn't in /dev directory. remount zvol to /var/lib/vz. To answer the LVM vs ZFS- LVM is just an abstract layer that would have ext4 or xfs on top, where as ZFS is an abstract layer, raid orchestrator, and filesystem in one big stack. (Install proxmox on the NVME, or on another SATA SSD). Fourth: besides all the above points, yes, ZFS can have a slightly worse performance depending on these cases, compared to simpler file systems like ext4 or xfs. Backups can be started via the GUI or via the vzdump command line tool. As well as ext4. For rbd (which is the way proxmox is using it as I understand) the consensus is that either btrfs or xfs will do (with xfs being preferred). Selbst wenn hier ZFS nochmals cachen tut, (eure Sicherheitsbedenken) ist dies genauso riskant als wenn ext4, xfs, etc. Crucial P3 2TB PCIe Gen3 3D NAND NVMe M. My goal is not to over-optimise in an early stage, but I want to make an informed file system decision and stick with that. . Why the hell would you someone on proxmox switch back to ext4? ZFS is a terrific filesystem, no doubt! But the issue here is stacking ZFS on qcow2. If no server is specified, the default is the local host ( localhost ). 8. It supports large file systems and provides excellent scalability and reliability. on NVME, vMware and Hyper-V will do 2. Install Proxmox from Debian (following Proxmox doc) 3. Ability to shrink filesystem. You will need a ZIL device. Create a zvol, use it as your VM disk. If you add, or delete, a storage through Datacenter. XFS fue desarrollado originalmente a principios de. Edge to running QubesOS is can run the best fs for the task at hand. Ext4 and XFS are the fastest, as expected. The ZFS filesystem was run on two different pools – one with compression enabled and another spate pool with compression. could go with btrfs even though it's still in beta and not recommended for production yet. data, so it's possible to only keep the metadata with redundancy ("dup" is the default BTRFS behaviour on HDDs). Add the storage space to Proxmox. use ZFS only w/ ECC RAM. This section highlights the differences when using or administering an XFS file system. For really large sequentialProxmox boot drive best practice. Unraid uses disks more efficiently/cheaply than ZFS on Proxmox. ago.
