I had the same problem described by kometen with our Areca ARC-1680 controller on opensolaris 2008.05. We were using the controller in JBOD mode and allowing zpool to to use entire disks.
Setting the drives in pass-through mode on the Areca controller manager solved the issue. Also worthy to note, after the zpool degraded under operation in JBOD and subsequently reconfiguring the controller to pass-through each disk, zpool import was able to recover the corrupted zpool. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
