Does this mean that sdd is failing and needs to be replaced? I sort of know the answer I'm going to get, but thought I'd check here first, in case I was missing something obvious.
Could be cable, controller, disk, or even some rare kernel bug, but it is probably the disk. If you can get the RAID1 sync'd and healthy again, you might try, shutting down, swapping the cables, and seeing if the problem follows the disk or the cable.
Actually, what I forgot to mention, is the two drives are attached to a PCI SATA-RAID controller card. I rebooted the computer after posting my last message, and on entering the card's setup, it appears the card has also got these drives setup as a RAID1 array (I must have set this up myself, sometime. Probably in a previous computer). I destroyed this array, so the two drives are independent at this level, and rebooted. This time, mdadm --manage is rebuilding the array again. After 90 minutes, it's showing #cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdd1[1] sdc1[0] 976759864 blocks super 1.0 [2/1] [U_] [===>.................] recovery = 17.9% (174884480/976759864) finish=550.0min speed=24294K/sec bitmap: 124/466 pages [496KB], 1024KB chunk unused devices: <none> so I'll be optimistic, and assume the two RAID setups were tripping over each other. If it fails again, I'll try your suggestion. Thanks.
