Trying to get xen to boot off of an iso or a sysresc image so I can expand a filesystem to the extent of the LVM's free space.
I have a Xen LVM based VM with two partitions:
/dev/VolGroup00/vm01p1
/dev/VolGroup00/vm01p2
p2 is about 50GB, I gave it's LVM an extra 30 or so using lvextend.
How can I extend the partition to fill my free space and the filesystem?
I don't mind offline, if I can get Xen to boot off an alternative media.

You can do that online using resize2fs (see above)

Does that require a kernel patch or is that information deprecated in CentOS 5.5?
Peter
Also, the filesystem is my /, how could that change life?

Hi Peter,
resize2fs just works with CentOS 5.5. In case of increasing the size of your filesystem that way you can do so online. FS shrinking will not work online or you would loose data.
resize2fs works for any mountpoint, including /. I have done that already several times. Just take care that the system is not heavily used at time of FS resizing. If you can afford run it in runlevel 1.
As always doing such kind of tasks: be prepared with a healthy, current backup and a disaster recovery strategy.
Regards
Alexander
