FSADM(8)       (LVM TOOLS 2.03.11(2) (2021-01-08))       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.
          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.

          -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|
               Absolute number of  filesystem  blocks  to  be  in  the
               filesystem, or an absolute size using a suffix (in pow-
               ers 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 filesys-
          tem it will be unmounted prior the resize.  All [y/n]  ques-
          tions 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.
