need help in recovering a RAID

["Thorsten Wolf" <T_Wolf@gmx.net>]

Hello again, everyone.

I've been really busy playing and working with mdadm tools lately. And I've come across a problem which I haven't been able to solve myself so far.

My system looks like this:
IDE:
/dev/hda1   -->   /      100 GB
/dev/hda2   -->   SWAP     1 GB
/dev/hda3   -->   /home  395 GB

S-ATA onboard:
/dev/hde1   -->   Disk 0 on /dev/md0
/dev/hdg1   -->   Disk 1 on /dev/md0
/dev/hdi1   -->   Disk 2 on /dev/md0
/dev/hdk1   -->   Disk 3 on /dev/md0

/dev/md0    --> via LVG mounted as /raid

A loose cable caused hdi and hdk to go offline. The server itself was shut down 1 minute later.

But I can't access the raid anymore because it marked the disks as failed. There was no write access to the system when the power went down on the two disks.

How can I mark them as online (I'm pretty sure the data is still ok) ???

I really want to get the raid working again as I think this is a good scenario that I'd like to be able to handle in the future.

Regards,

Thorsten
