Raid Failure??

[kurtg]

My system crashed, and then when I rebooted it took an interminably long time. So, I've been trying to recover it with the live cd. I believe I was using raid tools earlier, but now I'm using mdadm. I set up the devices and I'm getting these errors:

It looks like it's resyncing and will take 11+ hours to finish? Can that be right?

Is my /dev/sda drive whacked?

Not too good with raid here but if one of the drives is okay then format and just copy / clone it and it should be faster than resync.

UBCD google for it and use it to check the actual drive for fitness ? / is it dying or not.

Not sure where you can get a controller test program to verify if the raid controller is dying or not.

Might be a good idea to use a external hd / usb hd to backup your working hd to incase it is the controller or 1 of the actual hd's.

? Can you chroot into the install system from the live cd and then use the installed / merged programs to fix it ? Might have to load a few modules.

chroot how-to in link above.

Hope this helps.

I see you have both sata and ata hd on the raid ?

Not sure if this is a good idea as far as I know it has to be 100% same model make speed size etc .

No, they are both SATA drives. I think that's just a log message that says 'ata.1'. I'm not sure why.

I had Linux Soft RAID 1 on 2x500Gb HDD full of data and re-sync took around 2 hoers
As in post above try to reformat partition on failed hdd and use dd if=/dev/sda1 of=/dev/sdb1 for example.

What about the media write errors? It looks to me that the drive has simply gone bad. I have two new drives on order (upgrade to 250Gb), so I'll set them up when they come.
