FSADM(8)                                                        FSADM(8)

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.
