When running fsck I get this message: <snip> 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? -- Morten A.
