I'm having a problem adding disks to my root partition, which is using

root partition, but I can't figure out how to unmount the root
partition to do so.
The longer version of the story... I'm running Fedora Core 2, and
when I installed I had the root partition configured to be on two
disks using LVM. I added two more disks to the computer and followed
the howto to initialize the disks, add the physical volumes to the
volume group, and extend the logical volume. When I run "lvdisplay" I
see my logical volume is the correct size, but "df" only shows the
original size. I'm assuming this is because I haven't done a
"resize2fs". The reason I haven't is because I can't figure out how
to unmount the root filesystem in order to do this. If I boot with
linux rescue, I can choose not to mount the filesystems, but then the
LVM devices don't exist. I read somewhere that running "lvm vgscan -v
--mknodes" should do the trick, but as far as I could tell, no devices
were created.
Any ideas on how I can get the root partition resized to include the new disks?
Hi Jonathan,
if you take a look to the list-archive, you'll find more detailed answer.
In short, boot from a recovery media / Live-CD ( you can't umount root
to resize the fs! ), resize your rootfs, reboot.
Ciao
Klaus
