fsadm

utility to resize or check filesystem on a device

fsadm [options] check device

fsadm [options] resize device [new_size[BKMGTEP]]

fsadm utility checks or resizes the filesystem on a device. It tries to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesystem.

-e, --ext-offline

Unmount ext2/ext3/ext4 filesystem before doing resize.

-f, --force

Bypass some sanity checks.

-h, --help

Display the help text.

-n, --dry-run

Print commands without running them.

-v, --verbose

Be more verbose.

-y, --yes

Answer "yes" at any prompts.

new_size

Absolute number of filesystem blocks to be in the filesystem, or an absolute size using a suffix (in powers of 1024). If new_size is not supplied, the whole device is used.

On successful completion, the status code is 0. A status code of 2 indicates the operation was interrupted by the user. A status code of 3 indicates the requested check operation could not be performed because the filesystem is mounted and does not support an online fsck(8). A status code of 1 is used for other failures.

Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes. If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted prior the resize. All [y|n] questions will be answered ’y’.

fsadm -e -y resize /dev/vg/test 1000M

TMPDIR

The temporary directory name for mount points. Defaults to "/tmp".

DM_DEV_DIR

The device directory name. Defaults to "/dev" and must be an absolute path.
