FC4 Up to date

I went to do an Upgrade to FC5 and I don't have enough room on my system (which is a VMware Instance). So I thought well lets just extend the Logical Volume. The only problem is that LogVol00 is mounted to /. My head is sore from trying to find a way to run resize2fs on this LV when it is mounted on /. Is this even possible? I guess I could create a new LV in VolGroup00 and mount it to /var, but I started down this road and I'm kinda hoping I can figure it out.

So far I've done:

pvcreate /dev/sdb
vgextend VolGroup00 /dev/sdb
lvextend -l 267 /dev/VolGroup00/LogVol00 /dev/sdb
all worked fine, but of course:

resize2fs /dev/VolGroup00/LogVol00 - doesn't work because its mounted.

Any suggestions would be great. I am working out the /var to a LV thing but...

You can try this:

# ext2online /

However, with a size change as big as that it probably won't be able to help you. You'll need to boot from the rescue/install CD to resize the filesystem using resize2fs.

Well I'm up for that (rescue), but how? I did try that and I couldn't figure out how to call the /dev/VolGroup00/LogVol00 with resize2fs.
