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 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.
