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 said
mdadm --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
