fsadm

Check or resize a filesystem on a device. More information: https://manned.org/fsadm.

• Check a filesystem for errors:

fsadm check {{/dev/vg_name/lv_name}}

• Perform a dry-run resize to a specific size (no changes made):

fsadm {{[-n|--dry-run]}} resize {{/dev/vg_name/lv_name}} {{10G}}

• Grow a filesystem to fill the entire device (omit the size):

fsadm resize {{/dev/vg_name/lv_name}}

• Resize the filesystem and the underlying logical volume together:

fsadm {{[-l|--lvresize]}} resize {{/dev/vg_name/lv_name}} {{100G}}

• For ext2/3/4, unmount and resize offline:

fsadm {{[-e|--ext-offline]}} resize {{/dev/vg_name/lv_name}} {{20G}}
