After manually setting up LVM I forgot to update /etc/fstab. This meant my drives weren’t mounted on rebooting, which caused some worry!

Running as root you can get all the information you need to create the fstab entries using lvdisplay This will product something like

  --- Logical volume ---
  LV Name                /dev/sync/guitar
  VG Name                sync
  LV UUID                vIl1Lb-bVRh-SJPo-KdGd-1wIS-fUfl-J3bgW3

Either the LV Name or LV UUID can be used in fstab e.g.

# LVM Volumes -run lvdisplay as root to see where these come from
#<file system>	 <mount point>		<type>	<options>       <dump>  <pass>
/dev/sync/guitar  /var/sync/guitar	ext4	defaults	       0	     1

Now to load /etc/fstab run mount -a as root.
