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 (can be also dm-crypt encrypted
       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.

       -l|--lvresize
              Resize also given lvm2 logical volume.  More  volume  management  functionality  is
              provided with complementary lvresize(8) and the option -r|--resizefs.

       -n|--dry-run
              Print commands without running them.

       -v|--verbose
              Be more verbose.

       -y|--yes
              Answer "yes" at any prompts.

       -c|--cryptresize
              Resize  dm-crypt  mapping  together with filesystem detected on the device. The dm-
              crypt device must be recognizable by cryptsetup(8).

       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.
