I just noticed another thing. The two arrays should be identical in size,
although they are not:

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: 1430400MB (2929459200 sectors) RAID 5 (optimal)
amr1: delete logical drives supported by controller

Is it perhaps possible to change the partition info to match the old
functioning array?
