FSADM(8)                                                              FSADM(8)
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  crypt-
              setup(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.
