[cobalt-users] HD failure cont'd

["Martin" <mbruinsm@xxxxxxxxxx>]

Hi,

A little while ago I asked for some help to find out what is wrong with my
HDs in my RAQ4, since one of them failed according to the Cobalt
Administration.
One suggestion was to run the fsck command. I did, and there were some
filesystem problems indeed. However, problems keep popping up (inode block
bitmap differences, wrong free inodes count for groups). Is it normal to
have those kind of problems all the time? I mean, when I fix those problems
in the morning, in the afternoon they are there again...

I did some research in the Cobalt knowledge base, and found that using "cat
/proc/mdstat" you should be able to find out which drive is messing up.
Since I am new to the Unix filesystem, could anybody tell me what the
following output means for me (can't find a man entry for mdstat)?

Personalities : [linear] [raid0] [raid1] [raid5] [translucent]
read_ahead 1024 sectors
md1 : active raid1 hda1[0] 768000 blocks [2/1] [U_]
md3 : active raid1 hda3[0] 205056 blocks [2/1] [U_]
md4 : active raid1 hda4[0] 28879616 blocks [2/1] [U_]
md6 : active raid1 hda6[0] 131456 blocks [2/1] [U_]
unused devices: <none>

Thanks,

Martin
