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
