I got the pvcreate correct and the vgcfgrestore is present (though it was out of order with vgchange). Here is what I have done in detail: fdisk /dev/sdb (created three partitions of type LVM that are identical to those on the failed disk) mkfs.ext3 /dev/sdb1 mkfs.ext3 /dev/sdb2 mkfs.ext3 /dev/sdb3 (formatted as ext3) pvcreate --uuid xxxxx --restorefile /etc/lvm/archive/xxxx.ar /dev/sdb1 pvcreate --uuid xxxxx --restorefile /etc/lvm/archive/xxxx.ar /dev/sdb2 pvcreate --uuid xxxxx --restorefile /etc/lvm/archive/xxxx.ar /dev/sdb3 (chose archive file with all PV, LV and VG's from the functioning LVM setup) vgcfgrestore -f /etc/lvm/backup/VG_data VG_data (the VG_data matches the functioning LVM setup from above) vgchange -ay mount -t ext3 /dev/VG_data/LV_data /data gives "error: wrong fs type, bad option, bad superblock on /dev/VG_data/LV_data, or too many mounted filesystems" mount /dev/VG_data/LV_data /data gives "mount: you must specify filesystem type" Any suggestions regarding how to proceed.
