I have finally converted to logical volumes which leaves me learning a whole new world.  I was moving some data (500GB’s) between machines using a USB drive and found that the logical volume on the drive would not quickly mount via traditional mount /dev/sd… command.  So here is the process to mount a LVM.

1. Scan for the new volume (Assuming you added it after boot)

vgscan

2. Activate the volume

vgchange -a y VolumeName

3. Display the volume and confirm it’s active

lvdisplay

4. Mount the volume via it’s volume name

mount /dev/mapper/VolumeName /destination_mount_point

So you forgot to edit your fstab before you rebooted and now your stuck in read only / file system land… here’s the solution

Repair filesystem # mount -w -o remount /

Enjoy.
