Hints, Tips & Known Issues

Reinstall a machine Graham Titmus (27/01/2015)

To reinstall a machine that is currently working you can do so by copying a fresh image into a spare partition.

1. Login to the machine using your CL account
2. Check to see which partitions are available on the machine

cl-asuser blkid

1. Check which partition is in use at present

df /

1. Choose the device like /dev/sda? that is not currently in use - the disc may show up as a UUID which you check against the balked listing
2. Assuming /dev/sda2 is not currently in use then do the following (if /dev/sda2 is the current too then use dev=sda1 instead):-

dev=sda2
cd /a/misc-nosnap1/distros/ubuntu/clone/
sudo dd if=/dev/zero bs=512 count=3 of=/dev/$dev
sudo ./restore reinstall $dev

1. Restart the machine when the reinstall is completed
2. Check you can login
3. If the machine is to be given to someone different form the current owner then run replacing $crsid with their actual crossed i.e. gt19

cl-asuser cl-hostid-fix --user $crsid -a
