## 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  pro‐
              vided with complementary [**lvresize**(8)](https://www.chedong.com/phpMan.php/man/lvresize/8/markdown) 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)](https://www.chedong.com/phpMan.php/man/cryptsetup/8/markdown).

       _new_size_[**B**|**K**|**M**|**G**|**T**|**P**|**E**]
              Absolute number of filesystem blocks to be in the filesystem, or an absolute size  us‐
              ing  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)](https://www.chedong.com/phpMan.php/man/fsck/8/markdown).  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_ con‐
       tains  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.
