Hi All,

I have 3 120GB harddisks that are all part of an LVM group. One harddisk has physically failed (Can't even see it in fdisk -l) and now my entire logical volume is un-mountable.

# mount /share
mount: special device /dev/mapper/Vol1-share does not exist

I'm not sure about how to recover this... Obviously I've lost some data (There was over 240GB in use) but is it possible to save the rest of the volume?

I can't even remove the damaged PV as lvm see's it as "unknown device":

l# lvm pvscan
Couldn't find device with uuid 'VDIXIB-QE60-PrqH-4YqO-aXud-6XfA-7922zu'.
Couldn't find device with uuid 'VDIXIB-QE60-PrqH-4YqO-aXud-6XfA-7922zu'.
PV /dev/hda4 VG Vol1 lvm2 [106.79 GB / 0 free]
PV /dev/hdb1 VG Vol1 lvm2 [111.75 GB / 0 free]
PV unknown device VG Vol1 lvm2 [114.49 GB / 0 free]
Total: 3 [333.04 GB] / in use: 3 [333.04 GB] / in no VG: 0 [0 ]

Any advice on how I can recover this?

Thanks, Nick

what happens when you do "pvmove /dev/hdx"?

Hi, it just can't see the disk

# pvmove /dev/hdd1
Physical volume /dev/hdd1 not found
pvmove: Move extents from one physical volume to another

Then I would make sure that the device file name has not been changed, and all the cables are in firmly.
