I wouldn't use ZoL either -- I read that mailing list for quite awhile too, and skimmed most of the issues on GitHub. As of about six months ago, lockups were too frequent for my taste. All the implementations are improving though and the OpenZFS movement is promising. A caution here too: if you use ZFS, all implementations are not equal, you'll need to research the specifics for each platform on which you intend to use it; and the compatibility [with other implementations] if you want to move the file system [to a different platform]. If I was rolling out ZFS, I'd only use it on Illumos/OpenIndiana (vs., say ZoL).

I have been waiting and watching for a long time for most of these "new" filesystem features (pools, fs-level RAID, checksums, send/receive), but I am a "filesystem conservative" (especially in production; less so on my own machines) -- I'll keep waiting awhile longer. On production Linux today, I stay with EXT4 or XFS.
