I made it this way: http://ubuntuforums.org/showthread.php?t=464758
After installing dmraid and debootstrap I can see in gparted the two single /dev/sda and /dev/sdb. Also /dev/mapper/sil_.... During this phase nothing is formatted but partitiones. Later, when the installation started, and the partitioning seems to work (see my link above). The conclusion shows that the single partitions will be formatted this way: "LVM VG sil_..." The installation breaks, with the message (similar...): "Trying to write a file sytem, type swap, failed. ... could not be mounted". After this - starting gparted - I can see that changes happened on sda and sdb... So it seems to me, that swap cannot be handled in /dev/mapper/sil_.... -- dmraid says mirroring but isn't https://bugs.launchpad.net/bugs/129285 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
