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?
