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.

   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.
