Sorry to come back late in this thread. As other contributors pointed out correctly, the problem was RAID metadata at the beginning. > The > only > problem now is that the Ubuntu server CD wants to format /dev/sda2 as swap > and > fails at that stage. :-/ > > Not sure how to by-pass this. Yes. Most of the installers suck at that game. What I would do (already done this way) is: - install the disks in another machine with virtualization capacity; - create the RAID 1 (metadata=0.90); - create a virtual machine with the built RAID as single disk; - boot on the CD to install any distro; - move the disk out to the target bare metal machine; - update fstab and grub if needed. This has the advantage to not require to bypass the installer at some stage at the price of a temporary installation of the disks somewhere else. > I may > also try metadata=1.0 to see if this makes a difference, which also > positions the RAID data superblock at the end of the device: > > Sub-Version Superblock Position on Device > ----------- ----------------------------- > 0.9 At the end of the device > 1.0 At the end of the device > 1.1 At the beginning of the device > 1.2 4K from the beginning of the device > > To bypass the swap format you could try either deselecting the format > option (if it exists) or setting the partition type to something else. > The partition type can be set back to swap later from a livecd without > having to reinstall. > > Other option: > 1 install to single disk > > 2 using sysresccd create a degraded raid1 using the 2nd drive > > 3 copy the partitions and date from drive 1 to the degraded raid device What is "copy the date"? > 4 add disk 1 to the raid I might miss something but I guess you're going to erase the installed system (on disk 1) from the unused disk (disk 2), here. I believe it would only be possible by installing the system on the degraded RAID, which will likely mean coming back to the original swap problem. > 5 wait for the raid device is synchronized > > 6 change fstab and grub config to reflect the new disklayout -- Nicolas Sebrecht
