Problem with RAID following update
I am by no mean a Linux or Xen expert but I will do my best to explain my problem.
We had recently a problem with Xen. It kept posting some weird messages so before trying to fix the problem, I tried to update it with apt-get upgrade (I think Xen is running on Debian Etch but I am not sure since I am not the one who installed it).
At some point during the update, I was asked some weird question about arrays. I think I selected activate all arrays, but I did not know what I was doing.
When I rebooted, a lot of raid partitions that where in /dev/md* where transferred to /dev/.static/dev/md*
Because of that, I can't seem to be able to start my virtual machines who where running on those partitions (because Xen is looking for them in /dev/md* and not /dev/.static/dev/md*).
I am not sure what to do to bring back the old configuration. At start up with Grub, I have the option to choose from Xen 3 (our current version) or Xen 2.x (our old version). When I start Xen 2.x, all the necessary drive are in /dev/md* and I think there is nothing in /dev/.static/
In Xen 2.x, I ran mdadm --detail –scan, and copied the content of the file in /etc/mdadm/mdadm.conf in Xen 3. The missing partitions became available and I could even mount them and see the content of the directories but my virtual machines still won't start. I think that’s because there is still some stuff missing which is located in /dev/.static/
Therefore, all I would like to know is how I can put back my drives in /dev instead of /dev/.static
Thanks a lot for your help.
