Verify, that device-mapper is properly installed. To diagnose it, please run the lvm command with -vvvv and add output here.

Calling udev_complete internally to avoid process lock-up." This decrements the value of the semaphore used for synchronization. However, if the event (for some reason) *is* generated despite the fact that the kernel function responsible for sending the uevent reports a failure and then we decrement the value once again from within the udev rules based on the generated event (/lib/udev/rules.d/95-dm- notify.rules), we can end up with that: "semid 32768: semop failed for cookie 0xd4d83af: incorrect semaphore state..." The other messages about "... not set up by udev. Falling back to direct node creation" is just a consequence of failed synchronisation with udev (since we decremented semaphore value prematurely). However I'm not quite sure now why this happens. It could be a bug in kernel code as well... (but I can't reproduce that) Reply at: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/797226/comments/10 ------------------------------------------------------------------------ On 2011-03-31T15:31:04+00:00 Harald wrote: you might also try the new udev version in F15 Reply at: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/797226/comments/11 ------------------------------------------------------------------------ On 2011-04-11T15:05:54+00:00 G. wrote: New version in F15 seems to have solved the problems.
