Today I managed to boot this system again, so here are some updates: * the mount error (invalid argument) was caused by a missing "-t reiserfs" (or "-t ext2" for my /boot partition) * with "break=premount", the raid array has been correctly assembled twice (out of 4 tries), in which cas the LVM volumes have been correctly detected as well. * None of my "normal boot" (i.e. without break=[pre]mount) could assemble the array
I attach the output of udevd, corresponding to a boot where the RAID array has been assembled in degraded mode (resync is ongoing right now) ** Attachment added: "udevd --verbose output" http://librarian.launchpad.net/6387250/udevd-output -- [feisty] mounting LVM root broken https://launchpad.net/bugs/83832 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
