      Well, the results are in... the zoom barrel is spinning freely without actually adjusting the zoom, so the lens might actually be broken, but the modchip works!pic.twitter.com/pc3smXwTHP

      I don't know about favorite, but we're using Ceph, I think it's running on plain-old Ubuntu.

      I use multipurpose machines and want to use Linux, and don't trust the out-of-tree zfs module (or zfs in general); Ceph has some nice properties. So I'm experimenting with single-host Ceph.

      I haven't had a chance to try zfs-on-Linux, but it's been rock solid on FreeNAS. Snapshots alone are a pretty killer feature. Performance is lacking for Z2, the same way it is for hardware RAID6, but there are other configurations with better performance. I just chose redundancy.

      CephFS has snapshots (as does RBD), and can do arbitrary erasure codings decoupled from the actual number of disks. I trust the layered Ceph model than the single blob that ZFS is - if ZFS screws up my data is more than likely gone. Switched my backup server to Ceph already.

      In contrast, at home, I still have xfs on md-raid6 for now and performance is great (software RAID6 is very optimized these days). I did get myself into a SNAFU situation w/RAID6 once and was able to surgically fix it, since I *understand* RAID6. Can't say the same for zfs.
