How's the memory consumption of ZFS without deduplication these days? I've got a couple of 4 TB drives connected to a single board ARM computer with 2 GB of RAM. I used to use btrfs, but switched to XFS after I accidentally filled up a drive and was unable to recover.
- rincebrain 6y agoZFS without dedup will just run slower with less RAM available for caching, up to a point (I think the lowest I've seen someone run it with ARC configured to use in recent memory is 128 MB? I believe 32 MB or so is the minimum below which OpenZFS will just ignore you if you try to tell it to use less...) I've seen people use it as a rootfs on RPis, and have personally run it on Pis for brief occasions without encountering any RAM problems.
