Topic: Raid Problem

[Tim Hogan]

I posted this in the experienced users forum by mistake, I am reposting it here.

I installed raidmonitor and ran
/usr/local/bin/raidmonitor -iv
I received the following report:

It seems under the personalities section it should read
md1 : active raid1 hdb6[1] hda[0] 38796864 blocks [2/1] [UU]
rather than
md1 : active raid1 hdb6[1] 38796864 blocks [2/1] [_U]

Is this telling me that hda has a problem?

At the end of the partition info it says:
/dev/hdd: unrecognized partition
No partitions found

I am not sure what /dev/hdd is refering to. Is this refering to hda6?

Also, is the order in the personalities section telling me that hdb is the main drive and hda the mirrored drive (I expected the opposite, unless there is really a problem with hda and hdb took over).

Should I replace hda or is there some tests I should run first?

Thanks,
Tim Hogan
