Hello everyone, Looks like the compatibility code in rc4 doesn't properly snapshot beta7 logical volumes (2.4.10 kernel). To reproduce, I did this: Install 0.9.1 beta7 tools pvcreate /dev/sdb2 vgcreate big /dev/sdb2 lvcreate --size 6G -n lv1 big vgchange -a n rmmod lvm-mod Install rc4 tools vgscan vchange -a y mkfs /dev/big/lv1 mount /dev/big/lv1 /data lvcreate --size 1G -n snap --snapshot /dev/big/lv1 (trigger COW to snapshot) And I get these messages: lvm -- _pv_get_number failed for rdev = 0 lvm -- giving up to snapshot /dev/big/lv1 on /dev/big/snap: couldn't prepare kiovec blocks (start probably isn't block aligned). Now that I can reliably reproduce on stock kernels/tools, I'm trying to trace it further. If anyone has ideas I'd love to hear them. -chris
