@Ky Thanks for the feedback. I was a little jaded when I wrote my post. I bit the bullet on Monday morning and went through the install again. First of all I booted into a Gparted Live CD and wiped all RAID Arrays and partitions. I rebooted into it again to check, and had to remove a new RAID array md127? which had been created. After that the disks were clear.
I then ran the installer, creating my partitions , but leaving a space at the end of the disk, after the last partition. In my case this was /dev/sd[abcd]4, and I left 1Gb (although I gather less will also work). The RAID arrays assembled OK and I could reboot after install. So, just confirming the workaround ... -- 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
