Can you run that lvcreate/lvremove again with "-vvvv" debug messages
together with the udevd debug log and the output of "dmsetup udevcookies"
at the end of the run (making sure there are no cookies in system before
the run, of course). This way we should see and pair the cookies that were
processed and the ones that remained. We should also see at which stage
of the lvm command execution the cookie left in the system is actually
created. Thanks.
