Hi, Ah, I see, reading is never the problem. Do a simple cd to a directory on an lv that has an active snapshot dd if=/dev/zero of=test bs=1M count=10000 And see how hard it is to remove a live active snapshot. You will find that lvremove hangs, you can press Ctrl-C, then try lvscan and it hangs - maybe 2.6.15.1 has fixed this? Would you let us know? Thanks.

I am using this on a Gentoo system using vanilla kernel 2.6.15.1, and my volumes don't experience 'heavy I/O' at the times I make backups, so it shouldn't be too bad.
