After an entire day lost trying to install 10.04.1 LTS on a brand new Dell PowerEdge R210 with two 500Gb drives, I found this bug report and followed Thomas Krause workaround (creating the last partition with 100Mb less, thus leaving 100Mb unused) and was finally able to boot.
I can't believe such a gross bug went released. An entire day of work lost. It should also be noted that during installation, grub offers to automatically install on one of the disks' MBR (/dev/sda in my case), when the correct thing to do would be to install it on both /dev/sda and /dev/sdb -- 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
