[linux-lvm] lvm2 pv failure

[linux-lvm] lvm2 pv failure

[Uk1ah Sm1th]

Hello-

I had one of the two drives in my LVM2 array fail. It was the first
drive. Is it possiable that any data on the second drive could be
recovered? Or have I lost all my data on both drives?

All the logical volumes on the remaining drive should be recoverable.  
If you striped the two devices, you'll probably be hurting.  If the 1st 
hard drive is only partially failed (some sectors fail, others don't), 
then you should be able to retrieve most of that data too.

You could stuff in a new drive and 'dd' the contents of the failed 
drive to the new drive (if the drive hasn't completely failed) using 
the "noerror" option.

Now you might be able to (shutdown) pull the bad drive and reboot.

So far, you've risked nothing.  I'd see how this goes before trying 
other things (like editing the lvm labels directly).
