With no surprise the update from Interpid Ibex to** Jaunty Jackalope** was not as easy as I hoped. After booting the fresh 2.6.28 kernel I was welcomed with “Press enter for maintenance (or type Control-D to continue)” and errors when trying to mount my RAID0. After some investigations found that the devices are now named md_d* and there are some devices in /dev/md/.  Because of this change I had to do the following things to get my raid up and running:

  1. Reassemble the raid (check if it is inactive with less /proc/mdstat) – in my case the command looked like this: mdadm --assemble /dev/md_d1 /dev/sdb2 /dev/sda5
  2. mdadm --detail --scan >> /etc/mdadm/mdadm.conf and comment your previous ARRAY definition in the config file
  3. Modify /etc/fstab if needed

Also if DKMS fails to build the new NVIDIA driver be sure to check that you have installed the headers files (the upgrade process did not install them for me).

Again : I’m NOT responsible for any damage or data loss you might experience. Backup often, backup soon!

I’m in the same boat, but… I have no references to /dev/md0 in /etc/mdadm/mdadm.conf – in fact, aside from comments, it is quite empty.

Using mdadm -As finds the array, but brings it up with only 1 disk (i’m using raid-1)

/HUG Спасибо большое. Не Бог весть какая трабла, но меньше воскресного времени ушло на эту фигню :)
