Already making use of it, thank you! http://www.justinconover.com/blog/?p=17 I took 6x250gb disk and tried raidz2/raidz/none # zpool create zfs raidz2 c0d0 c1d0 c2d0 c3d0 c7d0 c8d0 df -h zfs Filesystem size used avail capacity Mounted on zfs 915G 49K 915G 1% /zfs # zpool destroy -f zfs Plain old raidz (raid-5ish) # zpool create zfs raidz c0d0 c1d0 c2d0 c3d0 c7d0 c8d0 # df -h zfs Filesystem size used avail capacity Mounted on zfs 1.1T 41K 1.1T 1% /zfs # zpool destroy -f zfs Or no raidz # zpool create zfs c0d0 c1d0 c2d0 c3d0 c7d0 c8d0 # df -h zfs Filesystem size used avail capacity Mounted on zfs 1.3T 1K 1.3T 1% /zfs So even though I''m loosing about 400gb of space, this is a backup server for my wife, a professional photographer, so loosing or photos might be worst than loosing space ;) This message posted from opensolaris.org
Is this a bug?

This shows 1.35TB of space
df -h /export/home/amy/
Filesystem size used avail capacity Mounted on
zfs/home/amy 915G 9.7G 905G 2% /export/home/amy
6x250gb would get about 1.3 but since its raidz2 its 4/6 right, so zpool
iostatus is reporting wrong.

I saw the same behaviour with plain RAIDZ. See this post: http://www.opensolaris.org/jive/thread.jspa?messageID=42716ꛜ This message posted from opensolaris.org
