NAME
fsadm — Utility to resize or check a filesystem on a device
SYNOPSIS
- fsadm
-
[options] check device
- fsadm
-
[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 that would change devices without running them. Read filesystem geometry and perform available read-only checks. Do not mount or unmount filesystems. Offline checks of mounted filesystems and ReiserFS checks that may replay the journal are skipped with a warning. A successful dry run does not guarantee that a later resize will succeed.
- -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.
