  • 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.


  • Meh. I run proxmox and other boot drives on ext4, data drives on xfs. I don’t have any need for additional features in btrfs. Shrinking would be nice, so maybe someday I’ll use ext4 for data too.

    I started with zfs instead of RAID, but I found I spent way too much time trying to manage RAM and tuning it, whereas I could just configure RAID 10 once and be done with it. The performance differences are insignificant, since most of the work it does happens in the background.

    You can benchmark them if you care about performance. You can find plenty of discussion by googling “ext vs xfs vs btrfs” or whichever ones you’re considering. They haven’t changed that much in the past few years.
