"I used the LiveCD to boot up, and used the package manager to download the dmraid package from the universe repository (enable the "Universe" source in the settings of Synaptic or by editing /etc/apt/sources.lst). ... If you install from the Live cd, install the dmraid package from universe before you start the installer program (Ubiquity). Just make sure you choose your RAID devices under /dev/mapper and do not use the raw devices /dev/sd* for anything. So far, I have heard from one user that Ubiquity then just installed the whole system as usual." -- ubiquity does not scan for software RAID (mdadm) devices like /dev/md0 during installation https://bugs.launchpad.net/bugs/112444 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
