Public bug reported:
Using the alternative cd I have been trying to install ubuntu on 2 disks
in a raid 1 linux software raid configuration. I would like 1 raid
device for boot and 1 for the rest(actually I would have the rest used
by LVM, but haven't got that far)
Something is confusing the partitioner or mdadm about my disks. It is 2
maxtor Diamondmax plus 9 120GB disks.
I can create the partitions fine. But when I then enter the raid
configuration. And choose to create a new raid 1...I get a message about
that no raid are available. If I then go to the terminal I can see that
it somehow has put all 4 raid partitions in one md device
I have 2 different controllers on my motherboard and have tried it on
each of them...with the same result.
I have also tried to install just normally on one disk, and then convert
it to raid...I cannot boot after I install mdadm
On the other hand I have tried the same alternate install cd on 2 old
ibm disks I had around where it works perfectly
I don't know, but what I can imagine is that somehow maybe the kernel
doesn't get the correct geometry of the disks? but that is just a wild
guess
I can install fedora core9 in the same raid configuration which are
failing with ubuntu. I have actually tried both 7.04,7.10,8.04 alfa 1 &
3 and also Debian etch. All of these versions fail with the maxtor disks
I will see if I can find out if there is any differences in kernel
parameters at boot time and/or kernel configuration

Hasse
