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.  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.
