does 9.04 ubiquity support RAID devices??

Asked by Pablo Marchant

Ive read that to install a system with a fakeRAID I need to use the alternate ubuntu iso for 8.10, cause ubiquity didnt had that option. Is it the same for 9.04?? The thing is, I installed my system using the 9.04 alternate ISO (cause I feared that the normal ISO wouldnt detect my RAID properly), but the installer gets stuck when I try to edit a partition (I want an ext4 partition, not the default ext3), and I was wondering if I could do this with the normal installer.

(Or if anyone knows how...how do I pass my ext3 raid device to ext4?? I havent found a way to do so, since the system is installed in the raid so i cant unmount it and change it to ext4, and also, Ive heard live cds wont detect the raid properly, so I cant change it that way...)

If you have setup the system in the past with success, why change?

for the record, fakeRAID sucks, get a RAID card and you can thank me later :D

As I mentioned...

The alternate installer didnt allow me to use ext4 because it got stuck when doing that. I could only install the system as ext3. I wanted to know if the ubiquity installer recognized RAID to see if I can choose ext4 there, cause I dont know how to change it in the instaled system

Um. I think that SATA-RAID sort of works in Ubiquity, although it may not be all that pretty.

However, Ubiquity is built on top of the alternate installer, so if the latter fails then it's unlikely the former will work. You should file a bug report on the debian-installer package in Ubuntu with the syslog and partman files attached from your attempt to use the alternate installer; you can extract those files by backing up to the installer main menu and selecting "Save debug logs".

Your comment about live CDs not detecting RAID only applies to real software RAID, not DM-RAID/fake-RAID/SATA-RAID (whatever you call it). Try it!

it seems like 9.04 has many trebles with loading from Software RAID on dmraid or mdadm:

clean install: https://answers.launchpad.net/ubuntu/+source/ubiquity/+question/71192
upgrade to 9.04: https://bugs.launchpad.net/ubuntu/+bug/358054

i try to install 9.04 on mdadm just yesterday, bug not Fix.

Can you help with this problem?
