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.

    but I found I spent way too much time trying to manage RAM and tuning it,

    I spent none, and it works fine. what was you’re issue?

      I have four 6tb data drives and 32gb of RAM. When I set them up with zfs, it claimed quite a few gb of RAM for its cache. I tried allocating some of the other NVMe drive as cache, and tried to reduce RAM usage to reasonable levels, but like I said, I found that I was spending a lot of time fiddling instead of just configuring RAID and have it running just fine in much less time.
