FSADM(8)                                                              FSADM(8)

       fsadm -- utility to resize or check filesystem on a device

       fsadm [options] check device
       fsadm [options] resize device [new_size]

       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.

              Unmount ext2/ext3/ext4 filesystem before doing resize.

              Bypass some sanity checks.

              Display the help text.

              Print commands without running them.

              Be more verbose.

              Answer "yes" at any prompts.

              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.

       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  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

       TMPDIR The temporary directory name for mount points. Defaults to "/tmp".

              The device directory name.  Defaults to "/dev" and must be an absolute path.
