I think the userspace LVM code could be tweaked to support this
configuration. Until then, you'll need to activate the snapshots
manually using dmsetup directly.
This would be fine.
Userspace changes we'd need for the tools (dmsetup) to support this:
Permit a snapshot to be activated without its corresponding origin.
- requires a snapshot exclusive lock (already supported)
- requires an origin lock that prevents any node having origin active
(implementation needs more thought but it should be possible)
So, thank you very much for your detailed explanation. Would
an implementaion change on "dmsetup" also solve the "Limitation of 32
snapshots" ?
Or is there a another possibility to fix/workaround this topic ?

Danny
