Confirmed here as well. I couldn't believe that such a fundamental bug would be released, but really, yes, my RAID system is unbootable after using the installer. Two and a half days wasted. I've got an IBM 3200 server with four 500Gb disks. My partitioning scheme is as follows. On each disk: /boot 1Gb / 15Gb swap 2Gb /home 482Gb Then I have a md0 RAID 1 on the four boot partitions (sd[abcd]1), md1 RAID 5 across the / partitions (sd[abcd]2) , md2 RAID5 across the /home partittions (sd[abcd]4)
The /etc/mdadm/mdadm.conf file looks correct before I reboot. After install I get the initramfs prompt. doing cat /proc/mdstat tells me only the md2 array is detected and its rebuilding. mdadm --detail /dev/md2 tells me that it is compose of sda, sdb, sdc, sdd ie the WHOLE disks I can do mdadm --stop /dev/md2 and then. mdadm --assemble /dev/md0 /dev/sd[abcd]1 mdadm --assemble /dev/md1 /dev/sd[abcd]2 mdadm --assemble /dev/md2 /dev/sd[abcd]4 After this the md2 only adds 3 of the 4 disks, but I can now boot by typing exit to get out of the initramfs. I've tried all my tricks to get this config to stick but apparently every reboot I have to manually stop the wrong array and manually assemble them all again. This is the amd/64 iso for ubuntu server 10.04. I also had the same problem with the 386 version. I've tried vaping the partition tables, reformatting the drives, and zeroing the superblock and none of these fix it. Two and a half days. Is the bug in mdadm, the partitioner, or what? -- mount: mounting /dev/md0 on /root/ failed: Invalid argument https://bugs.launchpad.net/bugs/569900 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
