Then the vgcfgrestore must have been unsuccessfull :( "vgchange -an" is not needed. It doesn't write to the PVs it just tries to deactivate the VGs in core. > > Is there any way of recovering the vg info from hdb onto hde ? vgcfgrestore! Look with "vgcfgrestore -ll ..." if your backup fits your config, run pvcreate -ff /dev/hde and vgcfgrestore -n data_disks -f /etc/lvmconf/YourPreferedArchive /dev/hde and vgscan ; vgchange -ay That should do the trick. The open question is, what overwrote your LVM metadata (and hopefully just it) on /dev/hde in the first place.
