Actually, both _could_ support online resizing if I ever got my butt in gear. As it is, only ext2 supports it, but ext3 has untested code to do it for 2.2 kernels. > You also don't know if anyone is using the volume for > a networked file system, which may screw things up > if the caching is too aggressive. No, never seen a problem with this. Nobody shrinks filesystems online, so at worst you might not fully utilize the newly allocated space. In the end, however, applications rarely check the total free space in a filesystem, but rather just write until the write command returns ENOSPC.
