I've been using RAID for a long time, but have been using the old raidtools. Having just discovered mdadm, I want to switch, but I'm having trouble. I'm trying to figure out how to use mdadm to replace a failed disk. Here is my /proc/mdstat:Personalities : [linear] [raid1] read_ahead 1024 sectors md5 : active linear md3[1] md4[0] 1024504832 blocks 64k rounding md4 : active raid1 hdf5[0] hdh5[1] 731808832 blocks [2/2] [UU] md3 : active raid1 hde5[0] hdg5[1] 292696128 blocks [2/2] [UU] md2 : active raid1 hda5[0] hdc5[1] 48339456 blocks [2/2] [UU] md0 : active raid1 hda3[0] hdc3[1] 9765376 blocks [2/2] [UU] unused devices: <none>The relevant parts are md0 and md2. Physical disk hda failed, which left md0 and md2 running in degraded mode. Having an old spare used disk sitting on the shelf, I plugged it in, repartitioned it, and saidmdadm --add /dev/md0 /dev/hda3
I think the thing to do is to list the md device before the --add : mdadm /dev/md0 --add /dev/hda3 I use the -a form and do: mdadm /dev/md0 -a /dev/hda3 Steve - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
