Here is the dmesg output before I re-created the array: amr0: delete logical drives supported by controller amrd0: <LSILogic MegaRAID logical drive> on amr0 amrd0: 1430505MB (2929674240 sectors) RAID 5 (optimal) amrd1: <LSILogic MegaRAID logical drive> on amr0 amrd1: 1430505MB (2929674240 sectors) RAID 5 (degraded) amr1: delete logical drives supported by controller as you can see, the volumes are identical -- Morten A.
