6 fsadm — utility to resize or check filesystem on a device
7
9 fsadm [options] check device
10 fsadm [options] resize device [new_size]
11
13 fsadm utility checks or resizes the filesystem on a device. It tries
14 to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesystem.
15
17 -e|--ext-offline
18 Unmount ext2/ext3/ext4 filesystem before doing resize.
19
20 -f|--force
21 Bypass some sanity checks.
22
23 -h|--help
24 Display the help text.
25
26 -n|--dry-run
27 Print commands without running them.
28
29 -v|--verbose
30 Be more verbose.
31
32 -y|--yes
33 Answer "yes" at any prompts.
34
35 -c|--cryptresize
36 Resize dm-crypt mapping together with filesystem detected on the
37 device. The dm-crypt device must be recognizable by crypt‐
38 setup(8).
39
40 new_size[B|K|M|G|T|P|E]
41 Absolute number of filesystem blocks to be in the filesystem, or
42 an absolute size using a suffix (in powers of 1024). If
43 new_size is not supplied, the whole device is used.
44
46 On successful completion, the status code is 0. A status code of 2
47 indicates the operation was interrupted by the user. A status code of
48 3 indicates the requested check operation could not be performed
49 because the filesystem is mounted and does not support an online
50 fsck(8). A status code of 1 is used for other failures.
51
53 Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes.
54 If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted
55 prior the resize. All [y/n] questions will be answered 'y'.
56
57 fsadm -e -y resize /dev/vg/test 1000M
58
60 TMPDIR The temporary directory name for mount points. Defaults to
61 "/tmp".
62
63 DM_DEV_DIR
64 The device directory name. Defaults to "/dev" and must be an
65 absolute path.
