FSADM(8)                 System Manager's Manual                 FSADM(8)
       fsadm — utility to resize or check filesystem on a device
       fsadm [options] check device
       fsadm [options] resize device [new_size]
       The  fsadm  utility  checks  or resizes the filesystem on a device
       (which can also be a dm-crypt encrypted device).  It tries to  use
       the same API for ext2, ext3, ext4, ReiserFS and XFS filesystems.
       -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
              Also resize the given lvm2 logical volume. More volume man‐
              agement 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 filesys‐
              tem, 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 MiB.
       If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be un‐
       mounted prior to 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.
