reiser3, resizable online in two ways (growing only)
        1)resize_reiserfs /path/to/dev 
        2)mount -o remount,resize /path/to/dev
To shrink reiser3 filesystem it must be unmounted.

XFS, MUST be mounted to resize use xfs_grow /mount/point
JFS, resizable online with a mount -o remount,resize /path/to/dev
ext2/3, resizable offline reliably.  Online resize is a *very* experimental 
experiment.  Have good backups.

For a good reference if one is ever needed to give to a friend, relative or 
foe try http://www.tldp.org/HOWTO/LVM-HOWTO/extendlv.html
