Charles,
Here's a snapshot ramdisk reference:
http://linuxsoftware.co.nz/blog/2008/03/11/lvm-snapshot-with-no-free-diskspace
The ramdisk has been working without problem. I tested it quite a bit
before putting it into production. But I don't know LVM internals so I
cannot say whether it could have had anything to do with the hang that
occurred.
Regards,
Gerry

My concern is that there is a bug somewhere in the snapshot
mechanism. I've seen other people report what they said were
corruption problems resulting from snapshots.
This is quite scary to someone like me who is new to LVM and using
snapshots for backups (whether automated or not)...
I'd really like to hear from some of the devs on this, and what they
think may have caused it...
Incidentally... this is the first time I've heard of someone using a
Ramdisk as the snapshot volume... any chance that could have been
involved somehow?
