Increasing LVM Size
Mothball, the BackupPC machine, needs more space to make an archive of a backup to be stored on DVD. The archive output directory is part of the root file system, so it can’t be edited while Linux is running. A live CD can help:
Boot Ubuntu 8.10 Live CD
Open a terminal
$ sudo -i
# apt-get install lvm2
# modprobe dm-mod
# lvresize --size 208G /dev/VolGroup00/LogVol00
If /dev/VolGroup00 doesn’t exist, reboot without the live CD
# resize2fs /dev/VolGroup00/LogVol00
