/proc/mdstat output

/proc/mdstat output

[Rene Scherer]

Hi all

I've got a small question about the output of "cat /proc/mdstat"

I've got 3 RAIDs configured (RAID-1 mirror), md0, md1 and md2
When I run "cat /proc/mdstat", I get the following output:

Personalities : [raid1]
read_ahead 1024 sectors
md1 : active raid1 sdb2[1] [dev 08:02][0]
      10241344 blocks [2/2] [UU]

md2 : active raid1 sdb3[1] [dev 08:03][0]
      38130176 blocks [2/2] [UU]

md0 : active raid1 sdb1[1] [dev 08:01][0]
      10241280 blocks [2/2] [UU]

unused devices: <none>

It looks like all 3 arrays are working fine (e.g. [UU]), but only 1
partition is listed (e.g. sdb1[1]). Why is it's mirror sda1 not listed?

Because of this webmin thinks all the sda disk are down. :-(

Any ideas?

Thanks,
Rene

It seems that the first partition is shown as [dev 08:02][0], which is
/dev/sda2 (for example). I have no idea why the name is not listed.
