# xfs_growfs

## NAME



           xfs_growfs - expand an XFS filesystem
    


## SYNOPSIS



           **xfs_growfs**[ **-dilnrx**] [ **-D** _size_ ] [ **-e** _rtextsize_ ] [ **-L** _size_ ] [
           **-m** _maxpct_ ] [ **-t** _mtab_ ] [ **-R** _size_ ] [ _mount-point_ | _block-device_ ]
    
           **xfs_growfs -V**
    


## DESCRIPTION



           **xfs_growfs** expands an existing XFS filesystem (see xfs(5)).  The
           _mount-point_ argument is the pathname of the directory where the
           filesystem is mounted. The _block-device_ argument is the device
           name of a mounted XFS filesystem.  The filesystem must be mounted
           to be grown (see mount(8)).  The existing contents of the
           filesystem are undisturbed, and the added space becomes available
           for additional file storage.
    


## OPTIONS



           **-d | -D** _size_
                  Specifies that the data section of the filesystem should be
                  resized. If the **-D** _size_ option is given, the data section
                  is changed to that _size_ , otherwise the data section is
                  grown to the largest size possible with the **-d** option. The
                  size is expressed in filesystem blocks. A filesystem with
                  only 1 AG cannot be shrunk further, and a filesystem cannot
                  be shrunk to the point where it would only have 1 AG.
    
           **-e** Allows the real-time extent size to be specified. In
                  **mkfs.xfs**(8) this is specified with **-r extsize=**_nnnn_.
    
           **-i** The new log is an internal log (inside the data section).
                  **[NOTE: This option is not implemented]**
    
           **-l | -L** _size_
                  Specifies that the log section of the filesystem should be
                  grown, shrunk, or moved. If the **-L** _size_ option is given,
                  the log section is changed to be that _size_ , if possible.
                  The size is expressed in filesystem blocks.  The size of an
                  internal log must be smaller than the size of an allocation
                  group (this value is printed at mkfs(8) time). If neither
                  **-i** nor **-x** is given with **-l** , the log continues to be
                  internal or external as it was before.  **[NOTE: These**
                  **options are not implemented]**
    
           **-m** Specify a new value for the maximum percentage of space in
                  the filesystem that can be allocated as inodes. In
                  **mkfs.xfs**(8) this is specified with **-i maxpct=**_nn_.
    
           **-n** Specifies that no change to the filesystem is to be made.
                  The filesystem geometry is printed, and argument checking
                  is performed, but no growth occurs.  **See output examples**
                  **below.**
    
           **-r | -R** _size_
                  Specifies that the real-time section of the filesystem
                  should be grown. If the **-R** _size_ option is given, the real-
                  time section is grown to that size, otherwise the real-time
                  section is grown to the largest size possible with the **-r**
                  option. The size is expressed in filesystem blocks.  The
                  filesystem does not need to have contained a real-time
                  section before the **xfs_growfs** operation.
    
           **-t** Specifies an alternate mount table file (default is
                  _/proc/mounts_ if it exists, else _/etc/mtab_).  This is used
                  when working with filesystems mounted without writing to
                  _/etc/mtab_ file - refer to mount(8) for further details.
    
           **-V** Prints the version number and exits. The _mount-point_
                  argument is not required with **-V**.
    
           **xfs_growfs** is most often used in conjunction with logical volumes
           (see md(4) and lvm(8) on Linux).  However, it can also be used on
           a regular disk partition, for example if a partition has been
           enlarged while retaining the same starting block.
    


## PRACTICAL USE



           Filesystems normally occupy all of the space on the device where
           they reside. In order to grow a filesystem, it is necessary to
           provide added space for it to occupy. Therefore there must be at
           least one spare new disk partition available. Adding the space is
           often done through the use of a logical volume manager.
