Include snapshot output in filesystem snap data

We need information in the filesystem portion of the snap command to identify which JFS2 filesystems have snapshot logical volumes. Currently it is not possible to determine this from snap data.

    There is no registry systemwide of where snapshots exist. Snapshots exist only as part of the filesystem or the block device. This is something that should just be a scan of all LVs to see if they contain snapshots.

    This will list snapshots for all LVs that are part of volume groups which are online:

    (cd /dev ; lsvg -o | xargs -n1 lsvg -l | grep jfs | egrep -v 'jfslog|jfs2log' | cut -f 1 -d \ | xargs -n1 snapshot -q )

    You could also check signatures on the front of usb devices, or do other stuff; however, that one-liner is really what you're looking for.
