Did you (partially) bisect that or are you just guessing? The only one there possibly relevant is 7e507eb6432afdd798d4c6dccf949b8c43ef151c. > Previously good logical volumes cannot be mounted anymore, and new one > cannot be created. All failed with the error ... > "device-mapper: version ioctl failed: Inappropriate ioctl for device" What distribution? What version of udev package? 'lvm version' output? Provide long listing of /dev/mapper and any dm/lvm devices in /dev. Add -vvvv to your lvm command for better clues. > Is there a new LVM2 for this new dm ioctl or the dm is not right? There's no new dm ioctl.
