NAME

6       fsadm — utility to resize or check filesystem on a device
7

SYNOPSIS

9       fsadm [options] check device
10       fsadm [options] resize device [new_size]
11

DESCRIPTION

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

OPTIONS

17       -e|--ext-offline
18              Unmount ext2/ext3/ext4 filesystem before doing resize.
19
20       -l|--lvresize
21              Resize given device if it is LVM device.
22
23       -f|--force
24              Bypass some sanity checks.
25
26       -h|--help
27              Display the help text.
28
29       -n|--dry-run
30              Print commands without running them.
31
32       -v|--verbose
33              Be more verbose.
34
35       -y|--yes
36              Answer "yes" at any prompts.
37
38       -c|--cryptresize
39              Resize dm-crypt mapping together with filesystem detected on the
40              device.  The  dm-crypt  device  must  be  recognizable by crypt‐
41              setup(8).
42
43       new_size[B|K|M|G|T|P|E]
44              Absolute number of filesystem blocks to be in the filesystem, or
45              an  absolute  size  using  a  suffix  (in  powers  of 1024).  If
46              new_size is not supplied, the whole device is used.
47

DIAGNOSTICS

49       On successful completion, the status code is 0.  A  status  code  of  2
50       indicates  the operation was interrupted by the user.  A status code of
51       3 indicates the  requested  check  operation  could  not  be  performed
52       because  the  filesystem  is  mounted  and  does  not support an online
53       fsck(8).  A status code of 1 is used for other failures.
54

EXAMPLES

56       Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes.
57       If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted
58       prior the resize.  All [y/n] questions will be answered 'y'.

60       fsadm -e -y resize /dev/vg/test 1000M

ENVIRONMENT VARIABLES

63       TMPDIR The temporary directory  name  for  mount  points.  Defaults  to
64              "/tmp".
65
66       DM_DEV_DIR
67              The  device  directory  name.  Defaults to "/dev" and must be an
68              absolute path.
