Re: RAID1 always resyncs at boot???

[drtebi@drtebi.com]

Well,
I thought it was fixed, but I suppose I was wrong... 

OK, I admit I was a bit brutal, but anyway.
The problem is that I have power outages here once in a while, it's something
with the wiring in this appartment (yes, I am running this server at home,
have an UPS, but it only lasts 40 min.).
 
So I pulled the plug of the server to give it a test, to see if it comes back
up fine and will reconstruct the array right.

Everything comes back up fine, the RAID array starts reconstructing. But after
an hour or so I find this:

/proc/mdstat:
Nov 28 04:41:56 [kernel] md: md_do_sync() got signal ... exiting
Nov 28 04:41:56 [kernel] raid1: mirror resync was not fully finished,
restarting next time.

.
/bus1/target0/lun0/part1


in my log:
Nov 28 04:41:44 [kernel] hda: dma_intr: status=0x51 { DriveReady SeekComplete
Error }
Nov 28 04:41:44 [kernel] md: (skipping faulty
ide/host0/bus0/target0/lun0/part1 )
Nov 28 04:41:45 [kernel] hda: dma_intr: status=0x51 { DriveReady SeekComplete
Error }
                - Last output repeated 8 times -
Nov 28 04:41:56 [kernel] md: md_do_sync() got signal ... exiting
Nov 28 04:41:56 [kernel] raid1: mirror resync was not fully finished,
restarting next time.

Does this mean one of the drives is bad?

The last message is weird... no md super block?

Thanks,

P.S.: I don't really like IDE drives :(
