Freezing the fs looks to make the log zero. So assigning any device/file for the external log would work. My mistake was not making the log dev an LVM. However I don't if a log on an LVM would have worked anyways.
It wouldn't work. If you snapshot a filesystem (XFS or Ext4) with an external journal, you'll need to create a new one or modify the snapshot to specify no journal.
Ah, good to know. So the method I found, actually one suggested to me from the XFS list was the only solution.
I've started a project to handle these things automatically and make it easier for everyone to make backups using snapshots. Initial work is here, and I'll be picking it up again when I'm back from Prague.

I'll be adding support for XFS, NetApp, and btrfs soon.
Nice info man, thank you very much.
