Good evening guys, hopefully you can help me with something I'm a bit stuck on!
I've been Googling for a few days now to see if I can find a solution, but having no luck at all. If someone has already raised this issue, then I apologise and ask that you point me in the right direction.
Right, the problem I have seems to be with disk detection/booting.
The system I am working with was previously running 9.10 (or similar), but using fakeraid (previous windows install that I wanted a dual boot for).
I used the 10.10 alternate cd to attempt an install. All well until disk detection. No disks were found (despite the fact that the fakeraid controller was running in "normal", non-raid mode). I couldn't get it to find the disks at all, no matter what I did. I gave up and used the 10.04 alternate cd to install 100% successfully. No problems at all on 10.04.
The disk configuration I setup on this fresh install was:
30gb (os1 - bootable) raid1 (mdadm)
30gb (os2, not formatted) raid1 (mdadm)
about 100gb (data, /home) raid1 (mdadm)
3gb (swap) raid1 (mdadm)
10.04 was working perfectly and I applied all the updates.
I then changed my update settings to include "all releases", not just LTS.
The online update was used to download, install and reboot 10.10
There were no errors and the system prompted for restart.
Upon reboot, the system will not boot.
It gets to grub and then drops to shell after giving up waiting for the boot device.
It also states that it couldn't find a device (/dev/disk/by-uuid/ID).
I couldn't do anything in that shell because it couldn't even detect the drives, let alone the partitions.
I used the 10.04 live cd to boot. I installed mdadm and gparted.
Using mdadm, I assembled a md0 from sda1 and sdb1 (my system partition). This worked and I was able to mount it. I checked the file system and all looks good.
The bottom line seems to be that something has changed in 10.10 that was fine in 10.04.
I used the online upgrade tool to ensure I was getting the most up-to-date packages (rather than the alternate cd) hoping that the issue has already been detected and resolved.
It's strange because the system partition is obviously readable as grub loads! But that's as far as it gets and it dies right there before it can actually start to boot.
The sata disk controller is a Silicon Image SATARAID 3114 device, but is NOT configured for RAID, just conventional drives. Various Google results inform me that there are no linux drivers needed for this these days as these are supported in the kernel. As I said before, 10.04 was quite happy to detect the drives and setup all the partitions etc. It's 10.10 that seems to have a complete inability to even see the disks!
Your suggestions please!
Many thanks,
John
