(Postet originally to Mint's buglist by me, but in case it can help someone, I copy-paste it here)
Finaly, after many hours I came to a workaround that actually works. To anyone interested: 1) Boot with a previous version that works (ex Karmic) and create the desired partitions 2) Boot with Lucid and start installation. Format the partition and set mount point, but do NOT create-delete any partitions. 3) At the last step, choose "Advanced" and select "do not install bootloader". (It wouldn't install anyway, no matter what you choose it just tries to install on /dev/sda). 4) Installation will finish, but do not restart. Open a terminal and let's chroot into our fresh installation. sudo mkdir /mnt/root sudo mount /dev/mapper/isw_jfighfbah_My_RAID3 /mnt/root sudo mount --bind /dev /mnt/root/dev sudo mount -t proc proc /mnt/root/proc sudo mount -t sysfs sys /mnt/root/sys sudo mount -t devpts devpts /mnt/root/dev/pts sudo cp /etc/resolv.conf /mnt/root/etc/resolv.conf sudo chroot /mnt/root /bin/bash now there's the key: ls /dev/mapper returns corrects results: /dev/mapper/isw_jfighfbah_My_RAID /dev/mapper/isw_jfighfbah_My_RAID1 /dev/mapper/isw_jfighfbah_My_RAID3 ... But if you try to execute grub-install /dev/mapper/isw_jfighfbah_My_RAID it will fail. (Aaargh I almost smashed the computer with this one..) I finaly discovered that although we can mount and chroot into the installation, not everything is OK with initrd image and dmraid. So, let's create the image again: apt-get purge dmraid apt-get install dmraid grub-install /dev/mapper/isw_jfighfbah_My_RAID update-grub You have now a perfectly working fresh installation of Mint 9 or Ubuntu 10.04 ;) Hope I've helped in any way... -- Ubuntu 10.04 can't create partition on fakeraid https://bugs.launchpad.net/bugs/568050 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
