I'll bring up that use case with Dan Phillips, see what he says. Heh. You cheated. You're snapshotting devices already in LVM2, so it already has control. Perhaps the thing to do is to integrate ddsnap into lvm; that way one could choose between traditional lvm snapshots for compatbility, or spiffy new shared-storage ddsnap snapshots for scalability. If people try ddsnap / zumastor and think it's worth it, maybe we could have a look at merging it with lvm somehow. That would be an interesting job. - Dan _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
