# resize2fs

> Resize an ext2, ext3 or ext4 filesystem.

- 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}}`
