I have one physical hard drive, a Western Digital 400 Gb which is
currently 100% used by Fedora Core 5. It is an LVM volume that looks
like this:
[rlc@bobcp4 ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
359G 58G 283G 17% /
/dev/sda1 99M 16M 79M 17% /boot
/dev/shm 1004M 0 1004M 0% /dev/shm
I want to resize and repartition this nondestructively so there are 5
partitions. 3 of these will be the /boot, /, and swap partitions and
together will total about 119 Gb. The other 2 partitions will each have
approximately 119 Gb each. My goal is to put 3 different operating
systems on the hard drive.
Here is what I believe I need to do.
1. Boot the Fedora 7 DVD in rescue mode.
2. Do not mount the file system, instead just go to a shell prompt and
3. lvm vgscan
Gets the name of the volume group
4. lvm vgchange -a y /dev/VolGroup00
Activates the volume
5. e2fsck -f /dev/VolGroup00/LogVol00
Checks file system for errors
6. resize2fs /dev/VolGroup00/LogVol00 119G
shrinks the file system down to 119 Gb
7. fdisk
shrinks size of partition
8. lvresize -L -238G /dev/VolGroup00/LogVol00
Then reboot without the rescue CD and I should still be able to boot
Fedora Core 5 but the disk will have 238G of unpartitioned free space.
Does this sequence seem correct?
Thanks for any help you can offer!
