If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel and the file system supports on-line resizing.

Modern Linux 2.6 kernels will support on-line resize for file systems mounted using ext3 and ext4;

ext3 file systems will require the use of file systems with the resize_inode feature enabled.

Filesystem features: resize_inode
