resize2fs

Resize an ext2, ext3 or ext4 filesystem. Does not resize the underlying partition. The filesystem may have to be unmounted first, read the man page for more details.

• Automatically resize a filesystem:

resize2fs {{/dev/sdXN}}

• Resize the filesystem to a size of 40G, displaying a progress bar:

resize2fs -p {{/dev/sdXN}} {{40G}}

• Shrink the filesystem to its minimum possible size:

resize2fs -M {{/dev/sdXN}}
