Just to document, before I used `sudo -s ''` but this did produce an `/bin/bash No such file or directory`, now I need to use `sudo bash -c ''` to achieve that the command `` is run correctly
I got the HP CQ58 notebook with FreeDOS and - of course - installed Ubuntu on it. The installation went smooth, just after the final reboot the screen went black and did not show the graphical login screen. Also I could not switch to console login with pressing ALT+F1 or the like, screen just kept black. I tried the two things:
A single disk of my RAID5 failed, it reported that the erroneous device was /dev/sda. As I have three disks with the same size I did a ls -l /dev/disk/by-id to find the serial number of the drive which maps to /dev/sda. After I did that I could proceed to actually removing the device from the raid and replacing the hard drive.
Thanks to the cheat sheet at http://www.ducea.com/2009/03/08/mdadm-cheat-sheet/ I could do
mdadm /dev/md0 --fail /dev/sda1 --remove /dev/sda1
/usr/bin/VBoxManage startvm VirtualMachineName --type headless
VBoxManage list usbhost
