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.

              Resize given device if it is LVM device.

              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.
