Nope. No help at all. ;) I've been using snapshots for as long as CentOS/Whitebox 3 have been around (just transitioned away from Whitebox). I would very much like to get it working on my 4.1 systems. So you can create snapshots but not remove them under 4.1?
Kernel 2.6 with LVM2 (RHEL4) is very different than Kernel 2.4 with LVM (RHEL3). The device-mapper (DM) facilities provide snapshots, as well as software RAID-1 mirroring (instead of MD, which is also an option), resizing, etc...
Last time I checked, most of the LVM2/DM tools were getting there, as long as you didn't do more than one operation at a time (e.g., snapshot of a LVM2 RAID-1 mirror). If you did, that created a race condition.
I haven't messed with LVM2/DM since late last fall as a result.
