ZFS Fault Management Daemon Added To FreeBSD
ZFSD is the ZFS Fault Management Daemon. ZFSD deals with situations like drive faults in ZFS pools with hot-spares and replacements. This comes as the ZFS file-system support in FreeBSD continues to mature and is in quite a good state for ZFS outside of Oracle.
More details on ZFSD for FreeBSD can be found via this commit. The code is currently in the head for FreeBSD 11 but it isn't clear right now whether it will be back-ported to a future FreeBSD 10.x point release.
