Imre, your suggestion worked. I zeroed the first several MB of the disk and performed the mdadm --zero-superblock as recommended by ceg in bug #527401. I did the install the same, except I manually created the partition and did not create swap.
I then tried installing on RAID1 again, the only difference being the addition of a swap partition. All other options were the same as the single drive install. It fails with the "Invalid Argument" error. :( I'll try again with no swap partition. -- 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
