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.

       -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.
