About a year ago I switched to ZFS for Proxmox so that I wouldn’t be running technology preview.

Btrfs gave me no issues for years and I even replaced a dying disk with no issues. I use raid 1 for my Proxmox machines. Anyway I moved to ZFS and it has been a less that ideal experience. The separate kernel modules mean that I can’t downgrade the kernel plus the performance on my hardware is abysmal. I get only like 50-100mb/s vs the several hundred I would get with btrfs.

Any reason I shouldn’t go back to btrfs? There seems to be a community fear of btrfs eating data or having unexplainable errors. That is sad to hear as btrfs has had lots of time to mature in the last 8 years. I would never have considered it 5-6 years ago but now it seems like a solid choice.

Anyone else pondering or using btrfs? It seems like a solid choice.

        Are you backing up files from the FS or sre you backing up the snapshots? I had a corrupted journal from a power outage that borked my install. Could not get to the snapshots on boot. Booted into a live disk and recovered the snapshot that way. Would’ve taken hours to restore from a standard backup, however it was minutes restoring the snapshot.

        If you’re not backing up BTRFS snapshots and just backing up files you’re better off just using ext4.
