Reading the man page on resize2fs, it notes: "As of this writing, the
Linux 2.6 kernel supports on-line resize for filesystems mounted
using ext3 only." Yet when I used the LVM GUI app, it choked at this
step, saying it couldn't unmount the root filesystem. That's
understandable, but it raises the question: can one use resize2fs from
a commandline while running fedora with the root filesystem mounted?
In a similar situation, I booted from the DVD in "linux rescue" mode.
I found that when it asked whether I wanted it to find and mount
partitions, I needed to hit "skip". If I allowed it to mount the root
partition, I could not unmount it.
In rescue mode, the vgscan, etc commands are not directly present, but
the executable lvm is, which can do all those things. When you run lvm,
you will get a new prompt, where you type lvm commands.
I was able to resize the mounted filesystem without going into rescue mode.
This was a remote system where "hands on" was not available.
I exited the GUI with the LV at the desired size.
I then did a resize2fs /dev/VolGroup00/LogVol00 from the command line
as root.
It warned me but did it.
It took a while.
I used up a good amount of Tums but it worked as advertised.
Cheers
