FSADM(8) System Manager's Manual FSADM(8)
NAME
fsadm — utility to resize or check filesystem on a device
SYNOPSIS
fsadm [options] check device
fsadm [options] resize device [new_size]
DESCRIPTION
fsadm utility checks or resizes the filesystem on a device (can be also
dm-crypt encrypted device). It tries to use the same API for ext2,
ext3, ext4, ReiserFS and XFS filesystem.
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
Resize also 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 crypt-
setup(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 in-
dicates 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 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 ab-
solute path.
