I have a problem with kdiskfree. For my local file systems, it shows a couple correctly as ext3 while others show ? as the type.
I also have several nfs mounts. They all show ? for type; one of the mounts doesn't even appear on the list. If I remove that mount and add again, it still doesn't show. However, if I create a new mount, that shows, though ? as type instead of nfs. Very strange.
Running CentOS 5.5.
