Hi... After succesfully following the guide on installing software RAID 1 on a running ubuntu 10.04 system (no LVM), I decided to do the same on a server machine with LVM installed: http://www.howtoforge.com/how-to-se...-system-incl-grub2-configuration-ubuntu-10.04 The configuration as shown in the howto is identical to our server except for the server name. Of course I used our server name whenever it was written server1. After the command $ pvmove -i 2 /dev/sda5 /dev/md1 reached 100%, it displayed: ABORTING: Can't find mirror LV in servername for /dev/sda5 After this I couldn't do anything anymore. all LVM commands resulted with: "Command failed with status code 5." And the system became read-only. I had to reboot, and of course, changing the grub and fstab resulted in an unbootable system. So now I need to either continue the process, or restore the system. Is there a way to restore the previous state? I assume I need to load the live CD, install mdm, mount sda through lvm and somehow restore the system from the command line, but I have no idea how to do all this... anyone? Thanks, Danny
meanwhile... loading live CD Still no luck. I'm trying to restore the system to its former state, I need to mount sda in the live cd environment: The unknown device is the RAID md0 that was installed during the guide steps. Trying to activate the VG: Using Partial: Trying to mount: Okay, so I decided to try to remove the PV of the RAID from the LG. Trying to remove the physical unknown device: Here I stopped. Should I use the --force directive or not? How can I repair the LV root afterwards? Do all the read fails and i/o errors mean that the pvmove command which finished with ABORTING after 100% actually corrupted the original /dev/sda?
last update... Having a backup of the system, I did a vgcfgrestore of the backup inside /etc/lvm/backup. It seemed to restore the LVM system to its previous definitions, but when trying to mount, I get: Killed trying to mount again hangs with no output... Restarting shows again the same situation after following the guide until the pvmove command.
