NAME         top

       fsadm — utility to resize or check filesystem on a device

SYNOPSIS         top

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

DESCRIPTION         top

       fsadm utility checks or resizes the filesystem on a device.  It tries
       to use the same API for ext2, ext3, ext4, ReiserFS and XFS

OPTIONS         top

              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.

              Resize dm-crypt mapping together with filesystem detected on
              the device. The dm-crypt device must be recognizable by

              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         top

       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         top

       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

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