fsadm — utility to resize or check filesystem on a device
- fsadm
- [options] check device
- fsadm
- [options] resize device
[new_size]
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.
-
-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.
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.
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
- 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.
