PBS and btrfs

[Shazan]

Hello,

can a directory where a datastore is configured be based on BTRFS?
Did anyone try it? Any issues?

Thank you.

As long as the file system supports basic POSIX features every file system should work. BTRFS is POSIX.

Hi,

Cookiefamily is totally correct.

To add a bit on top of that: we have a bit bigger (100 TiB) setup which we tried with both ZFS and btrfs, they worked both pretty well when having in mind that the underlying disks are spinners.

I'd recommend using the newer 5.11 kernel (available as opt-in for PBS similar to PVE) and btrfs-progs from buster-backports, as it includes quite some enhancements in especially the btrfs area. But in general we did not see any real blocker, so it's fine to use if you prefer it, e.g., due to running it on other hosts already.

Thank you very much both.

Are there any news about the plans to offer a btrfs storage plugin in proxmox (pve/pbs)?
