NAME¶
fsadm — utility to resize or check filesystem on a device
SYNOPSIS¶
fsadm [
options]
check device
fsadm [
options]
resize device
[
new_size[
BKMGTEP]]
DESCRIPTION¶
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.
OPTIONS¶
- -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.
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 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
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.
