I apologize for not reading your initial post thoroughl= y and jumping on your suspicion that the hardware might be to blame. Did you really create one vdev of 25 disks? This is strongly discouraged by the documentation provided by Sun/Oracle. You should (IIRC) never have more than 9 disk in a single vdev. Of course you can join N vdevs of type, say, raidz2 to a single zpool. See for example http://forums.freebsd.org/archive/index.php/t-4641.html I'm writing from my iPad and cannot quickly find the Link to the Sun documen= tation. Kind regards, HTH, Patrick=
