Sigma rechip PCB's are in. Huge thanks to @marcan42 for generously open sourcing this mod. I've been wanting a 300mm lens since I first got my T5i.pic.twitter.com/LGDWUy8WzN

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.
