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. Unfortunately you will probably lose a few files in both cases. EXT4 is very low-hassle, normal journaled filesystem. data, so it's possible to only keep the metadata with redundancy ("dup" is the default BTRFS behaviour on HDDs). b) Proxmox is better than FreeNAS for virtualization due to the use of KVM, which seems to be much more. Created XFS filesystems on both virtual disks inside the VM running. 5. You also have full ZFS integration in PVE, so that you can use native snapshots with ZFS, but not with XFS. ZFS is nice even on a single disk for its snapshots, integrity checking, compression and encryption support. Please note that XFS is a 64-bit file system. 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. Wanted to run a few test VMs at home on it, nothing. LVM, ZFS, and.
