cat /proc/mdstat - how to tell what volumes its resyncing
 

I have another question about mdstat. Looking at the output of a cat /proc/mdstat, how do i know what volumes its actually resyncing? when i do a df -h everything appears to be there.


Personalities : [raid1]
read_ahead 1024 sectors
Event: 2
md0 : active raid1 sdb1[1] sda1[0]
859549696 blocks [2/2] [UU]
resync=DELAYED
md1 : active raid1 sdb2[1] sda2[0]
859533632 blocks [2/2] [UU]
[====>................] resync = 23.0% (198178176/859533632) finish=10578.9min speed=1040K/sec
unused devices: <none>

There's no issue. The fact that the full software resync between the two disks is in progress doesn't mean that it's unavailable, just that it won't be fully trustable in case of failure of the first disk. In your output, the sync is at 23% of completion.

but how do i know which volume the resync is going on for?
