Failed Boot Partition - LVM Series #3

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.

fdisk –lu

Scan all disks for physical volumes:

pvscan

Scan disks for volume groups:

vgscan

Activate all volume groups available:

vgchange -a y

Scan all disks for logical volume:

lvscan

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.
