resize2fs

Resize an ext2, ext3 or ext4 filesystem. Does not resize the underlying partition, and the filesystem must be unmounted.

  • 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}}
