I'd love to see the ability to instantiate a storage pool for creating snapshots, with either a first-in-first-out or even some other method for bumping snapshots when the pool fills up. The inefficiency of the former style of lvm snapshots in both space and speed and the cumbersome nature of managing them has kept me looking for alternatives. Btrfs isn't quite there yet and may not be through 2011 or beyond. zfs-fuse can't seem to act as a volume manager and I'm having problems with crashes. Frustrated, I'm turning back to lvm. So now I'm looking at the lvm wiki and I'm seeing "shared exception store". Can someone fill me in on the current status of this effort as the wiki was last updated in May-2009 ? Thanks!
