This one is fairly straight forward. This is what you need to do if your boot partition should fail and you need to remount the LVM logical partition in a new machine or once you’ve re-installed Ubuntu on a new boot partition.Make sure the HDDs are recognised.
Scan all disks for physical volumes:
Scan disks for volume groups:
Activate all volume groups available:
vgchange -a y
Scan all disks for logical volume:
Now mount the partition to any directory you want:
mount /dev/fileserver/shared /raid/share
Amend fstab to mount persistently if required. See guidance from start of this mini-series.
