[linux-lvm] summary of what I need to do to mount snapshot on XFS

[Adrian Head]

The basic concept is you create a snapshot LV
lvcreate -L1G -s -n snap /dev/vg/lv1

This will create a 1G snapshot logical volume called snap for the original 
logical volume /dev/vg/lv1

If this has completed successfully then you can mount it.

mount -t xfs -o nouuid /dev/vg/snap /mnt/snapshot

This will mount an xfs snapshot.  The -o nouuid is needed so that mount will 
not complain and refuse to mount an xfs volume with identical uuid's

This is a good tutorial:

Is this what you are after or are you having problems with lvcreate 
segfaulting and kernel Oopes?
