FSADM(8)

NAME
fsadm — Utility to resize or check filesystem on a device

SYNOPSIS
[options] check device [options] resize device [new_size]

DESCRIPTION
The fsadm utility checks or resizes the filesystem on a device (which can also be a dm-crypt encrypted device). It tries to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesystems.

OPTIONS

-e|--ext-offline
    Unmount ext2/ext3/ext4 filesystem before doing resize.

-f|--force
    Bypass some sanity checks.

-h|--help
    Display the help text.

-l|--lvresize
    Also resize the given lvm2 logical volume. More volume management functionality is provided with complementary lvresize(8) and the option -r|--resizefs.

-n|--dry-run
    Print commands without running them.

-v|--verbose
    Be more verbose.

-y|--yes
    Answer "yes" at any prompts.

-c|--cryptresize
    Resize dm-crypt mapping together with filesystem detected on the device. The dm-crypt device must be recognizable by cryptsetup(8).

new_size[
    B|K|M|G|T|P|E] 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.

DIAGNOSTICS
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.

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

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

ENVIRONMENT VARIABLES

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.
