LVM One Harddisk died
Hallo,
I am a lvm running with several hard disks. One of the hard disks died.
What can I do, to have access to left data?

LVM1, I assume ?
Raplace the dead hard disk with one of the same size, pvcreate the new one and vgcfgrestore the data to it. Run "vgscan ; vgchange -ay" afterwards (which will probably run anyway in one of your boot scripts).
- Or -
Install device-mapper and LVM2 and use LVM2's partial activation feature (vgchange -ay -P). You must recreate the VG after you saved any data still accessible.
- Or -
if you want a quick hack taking the risk that accessing parts of logical volumes mapped to the dead disk (assuming your volume grous name is "VG" and that VG is the only one in the system):
# mkdir /etc/lvmtab.d # cp /etc/lvmconf/VG.conf /etc/lvmtab.d/ # echo -ne "VG\0" > /etc/lvmtab # vgchange -ay
That should get you temporary access to all data you still _can_ access. Save it and if you don't replace the failed disk, recreate your volume group, logical volumes and filesystems in order to restore your data.
