[linux-lvm] Crashed disk with LVM

[Hiamal]

Hi,

I have tow disks(hda and hdb) where tow partitions(hda2 and hdb1) a
part of one LVM group VG01.
Now disk hdb has crashed and I'am trying to save the data on hdb1 to
another disk.
I tried with knoppix dumping(dd) hda2(works) and hdb1(don't work) and
I also tried activating the lvm group and dd the lvm volume but when
dd comes to hdb1 the disk just hacks and sounds noisy :-P

What should I do?


/h

Instead of dd try dd_rescue. It's able to skip errors on failed disc and 
read the rest.

During dumping, prepare you regular backup plan ;-)

That was my backup server...

Anyway I solved the prob running ddrescue from a LiveCD dumping the
recovered data to a file on a new disk. It took
 ca 4 days for ddrescue to do the jobb. After that I had to mounted
the dumped file, activated the LVM vol's and was abel to recover
almost all the data.
