I''ll start: - The commands are easy to remember -- all two of them. Which is easier, SVM or ZFS, to mirror your disks? I''ve been using SVM for years and still have to break out the manual to use metadb, metainit, metastat, metattach, metadetach, etc. I hardly ever have to break out the ZFS manual. I can actually remember the commands and options to do things. Don''t even start me on VxVM. - Boasting to the unconverted. We still have a lot of VxVM and SVM on Solaris, and LVM on AIX, in the office. The other admins are always having issues with storage migrations, full filesystems, Live Upgrade, corrupted root filesystems, etc. I love being able to offer solutions to their immediate problems, and follow it up with, "You know, if your box was on ZFS this wouldn''t be an issue." -- This message posted from opensolaris.org

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!

The simplicity is interesting.

Huh? The very concept is so antiquated. The great success of ZFS, to me, is the fact that it rapidly became essentially invisible. It just does its job and you soon forget that it''s there (until you have to deal with one of the alternatives, which throws it into sharp relief). -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
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
