I had the same problem when converting from one disk to a RAID-1 setup. I added a break=mount and tried to start the arrays with "mdadm -A -s", but that didn't work.
The default configuration has a line "DEVICE partitions" in /etc/mdadm/mdadm.conf. This apparently doesn't work. (All my partitions are listed in /proc/partitions and the major/minor numbers match up to those in /dev) Adding the ARRAY lines to mdadm.conf and regenerating the initrd image worked for me. I'm using gutsy 7.10 x86_64 with Linux image 2.6.22-14-generic (all updates installed). -- [gutsy] mdadm, initramfs missing ARRAY lines https://bugs.launchpad.net/bugs/136252 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
