Hey guys, I ran into an odd issue with LVM and the wiping the drbd meta data from a logical volume. Here is what my wipe md command looks like, this is all done via a script:
drbdmeta --force num v08 /dev/vg0/vol100 internal wipe-md Which succeeds, but then when the script performs a back to back lvremove: lvremove -f /dev/vg0/vol100 I get this error a few times, but after a few retries of lvremove succeeds: Can't remove open logical volume "vol100" So I'm thinking even after the drbdmeta command returns, somehow there is still a file descriptor open on the logical volume. Could it be udev doing something? In my situation, when I remove the wipe-md command before the lvremove, the issue goes away completely. In a related question, is it necessary at all to wipe the drbd meta data? I did it to avoid those 'strange bm offset' messages, but could it cause problems if I just ignore wiping it? Thanks, Chris
