OK, my turn: - combining file system + volume manager + RAID + pool + scrub + resilvering + snapshots + rollback + end-to-end integrity + 256-but block checksums + on-the-fly healing of blocks with checksum errors on read - one liners that are mostly remembered, and simple to guess if forgotten - with RAID-Z2, superb protection + hot spares - easy sharing via CIFS and NFS - iSCSI as a block device target - open source software RAID no proprietary hardware RAID card required - free - did I forget something? :) -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Interesting. Usually the problems make their way to this list more than the successes. Glad to hear it! BTW, ZFS just saved my skin tonight after I botched an OpenNMS upgrade and was able to go back to my auto-snapshots :) And there was a power failure earlier that took down a bunch of hosts that rely on our multi-terabyte ZFS filer, as well as the filer itself - no waiting around for fsck, thanks!
