Commands that might be useful: pvscan - verify the physical disks are present vgscan - scans for volume groups vgchange -a y - activates all volume groups Now your logical volumes should be present and seen with 'lvscan' and so can be mounted (/dev/VolGroup/LVName would be the volume to mount) -- rgds Stephen
