[Bug 112444] Re: ubiquity does not scan for software RAID (mdadm) devices like /dev/md0 during installation
This problem still exists in Gutsy Gibbon. It is, indeed, most frustrating. Even after I manually created and formatted the raid1 partition (ext3), ubiquity still refuses to recognize them. Instead, its partitioner misidentifies both of the mirrors as plain ext3 partitions. I had to apt-get the mdadm utility. Then I did this: mknod /dev/md0 b 9 0 modprobe raid1 mdadm -v -C /dev/md0 --level=raid1 --raid-devices=2 /dev/sda7 /dev/sdb7 mke2fs -j /dev/md0 It all worked fine. But it made no difference to ubiquity. The install link on the desktop (ubiquity) still refused to recognize the md0 device at the partitioning step. -Dave http://www.burtonsys.com/email/ -- 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

[Bug 112444] Re: ubiquity does not scan for software RAID (mdadm) devices like /dev/md0 during installation
A very easy 75% solution would be to make the partitioner simply look for multiple hard disk drives (or partitions with with type = 0xFD), and if they are seen then display a warning message: *** Warning: This installer cannot install Ubuntu on a RAID partition. If you wish to install to a RAID partition (such as RAID1/mirrored), please shutdown/restart, and then at the boot-up menu select either Text-mode install or Install Ubuntu server. Obviously it would be better to fix it. But telling users how to work around the problem would be very simple to implement, and it would change the extreme frustration that this problem causes into a minor annoyance. (Note: those quoted menu choices in my suggested warning message need to be double-checked, as they are from my very fallible memory.) -Dave http://www.burtonsys.com/email/ -- 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
[Bug 112444] Re: ubiquity does not scan for software RAID (mdadm) devices like /dev/md0 during installation
I am having the same issue on the Feisty installer. It can see my encrypted RAID5 array on /dev/mapper/root which is mapped on /dev/md1 but it cannot see my plaintext RAID5 /boot array on /dev/md0. This is very frustrating. Does anyone know if this is fixed in a daily build of the gibbon release? -Brandon -- 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

Check the FakeRaidHowTo: https://help.ubuntu.com/community/FakeRaidHowto 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

dmraid is for FakeRAID. mdadm is for Linux-only software RAID and is a completely different concept. So, it still appears that my initial bug report is legitimate. -- 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
