fsadm: utility to resize or check filesystem on a device
NAME
fsadm --- utility to resize or check filesystem on a device
SYNOPSIS
-
fsadm
[options]
check
device
- fsadm [options] resize device [new_size]
DESCRIPTION
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.
- -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 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.
