Fortunately you can grow the size of a pool while it's hot, get some more LUNs allocated and just do a zpool add. Highly recommend it until there's a patch to add background defrag for ZFS pools. You're the first person I've read using iSCSI though doesn't that add a bunch of latency? And 7200 RPM SATA to boot. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
