1. Boot from live CD.
2. Open terminal window
3. Do not mount the filesystems
4. At the shell type: lvm
5. Within lvm shell, run following commands:
lvm> vgscan
lvm> vgchange –available y VolGroup00
lvm> lvscan # should show the LV as “ACTIVE”; the devices in /dev it mentions should now exist
lvm> exit
6. Now resize the filesystem with this command (e.g. using device /dev/VolGroup00/LogVol00):
e2fsck -f /dev/VolGroup00/LogVol00 # check filesystem
resize2fs /dev/VolGroup00/LogVol00 nnG # resize the fs to nn GB; nn should be less than the current fs size
e2fsck -f /dev/VolGroup00/LogVol00 # recheck filesystem
7. Run lvm again and type:
lvm> lvreduce -LnnG /dev/VolGroup00/LogVol00 # resize the LV to nn GB; nn should be the same as above
lvm> exit
8. Do another filesystem check:
e2fsck -f /dev/VolGroup00/LogVol00
9. Reboot and remove CD.
If you get the warning of resizing currently ACTIVE LV, please do the following from command line:
lvchange -a n VolGroup00/LogVol00 # to deactivate LV
and after operation above do:
lvchange -a y VolGroup00/LogVol00 # to reactivate LV
