There was recently a thread were someone had an issue importing a known-to-be-healthy pool after a BIOS update. It turned out that the new BIOS had a different host protected area on the disks and therefore delivered a different disk size to OS. I'd check the controller and BIOS settings that are concerned with disks. Any change in this area might lead to this effect. Additionally, I think it is not a good idea to use a RAID controller to mirror disks for ZFS. Like this a silently corrupted sector cannot be corrected by ZFS. In contrast if you give ZFS both disks as individual disks and create a ZPOOL mirror, ZFS is able to detect corrupted sectors and correct them from the health side of the mirror. A hardware mirror will never know which side of the mirror is good and which is bad... _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
