RAID0 on EG AMD server

I think the problem might be on the RAID configuration done before the installation was launched.

The RAID0 must be configured in rescue mode so that fdisk -l shows exactly 1 disk of the total size. Could you post the output of the RAID configuration, please?

say, the output for these commands will be perfect:
# tw_cli maint info c0
# fdisk -l

it looks like you've modified the RAID configuration using the rescue mode (correct me if wrong), but after that, you won't expect the server to boot up with your previous installation, will you? The RAID modification has deleted everything that was previously in the hd

Once the RAID has been modified to RAID0, RAID1 or JBOD, an installation must be launched right away. Then, the new system will be installed on the layout that you've selected before.

Hope this helps

I can change to raid0, but after the boot i cant use the server, it turns offline and I have to wait my ticket to solve the problem and when the server comes online again, raid1 is back and Ubuntu Desktop installed.
are you certain raid1 is back as you will have to extend the main partition
as it will still only use 1 the space allocated by the first disk so you have to extend the partition using something like gparted

you probably have got a server with LSI raid interface, try using lsiutil.
