With Proxmox you need a reliable OS/boot drive more than a fast one. 1. Any changes done to the VM's disk contents are stored separately. See Proxmox VE reference documentation about ZFS root file systems and host bootloaders . It can hold up to 1 billion terabytes of data. Ext4 seems better suited for lower-spec configurations although it will work just fine on faster ones as well, and performance-wise still better than btrfs in most cases. (You can also use RAW or something else, but this removes a lot of the benefits of things like Thin Provisioning. For a while, MySQL (not Maria DB) had performance issues on XFS with default settings, but even that is a thing of the past. iteas.

The ability to "zfs send" your entire disk to another machine or storage while the system is still running is great for backups. ZFS snapshots vs ext4/xfs on LVM. Storage replication brings redundancy for guests using local storage and reduces migration time. 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. 3 XFS. ext4 /dev/sdc mke2fs 1.
