Package: udev Version: 146-5 Severity: normal *** Please type your report below this line ***
I've setup a software (mdadm) raid on my system, but at reboot the system fails to build the raid array. The array is made of /dev/sdb1 and /dev/sdc1; those partitions spans over the whole disk. At boot time the system (usually) complains about /dev/sdc and /dev/sdc1 having a very similar superblock, and suggests to clear the fake one; however mdadm --zero-superblock does not solve. In this situation, /dev/sdc1 is not present neither in /dev/ nor in /proc/partitions, while /dev/sdc, /dev/sdb and /dev/sdb1 are there; moreover, fdisk -l /dev/sdc says that the partition exists on the disk. Sometimes the system builds a degraded array in /dev/md127 instead of /dev/md0, sometimes using /dev/sdb or /dev/sdc. I've googled for a solution, and the most similar issue I've found is in http://osdir.com/ml/linux-raid/2009-04/msg00358.html Tehy say it can be a race condition, and it seems to me coherent with the behaviour I'm seeing; however I couldn't find on my system the related udef file, so I couldn't use the proposed workaround. -- Package-specific info: -- /etc/udev/rules.d/: /etc/udev/rules.d/: total
