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.
