## NAME
       xfs_growfs - expand an XFS filesystem

## SYNOPSIS
       **xfs**___**growfs**  [  **-dilnrx** ] [ **-D** _size_ ] [ **-e** _rtextsize_ ] [ **-L** _size_ ] [ **-m** _maxpct_ ] [ **-t** _mtab_ ] [
### -R

       **xfs**___**growfs** **-V**

## DESCRIPTION
       **xfs**___**growfs** expands an existing XFS filesystem (see [**xfs**(5)](https://www.chedong.com/phpMan.php/man/xfs/5/markdown)).  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)](https://www.chedong.com/phpMan.php/man/mount/8/markdown)).   The existing contents of the filesystem are undisturbed, and the added space be‐
       comes available for additional file storage.

## OPTIONS
### -d -D
              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
              with **-r** **extsize=**_nnnn_.

### -i
              **implemented]**

### -l -L
              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)](https://www.chedong.com/phpMan.php/man/mkfs/8/markdown) 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
              allocated as inodes. In [**mkfs.xfs**(8)](https://www.chedong.com/phpMan.php/man/mkfs.xfs/8/markdown) this is specified with **-i** **maxpct=**_nn_.

### -n
              printed,  and  argument checking is performed, but no growth occurs.  **See** **output** **exam**‐‐
              **ples** **below.**

### -r -R
              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  ex‐
              pressed  in filesystem blocks.  The filesystem does not need to have contained a real-
              time section before the **xfs**___**growfs** operation.

### -t
              _/etc/mtab_).   This  is  used  when working with filesystems mounted without writing to
              _/etc/mtab_ file - refer to [**mount**(8)](https://www.chedong.com/phpMan.php/man/mount/8/markdown) for further details.

### -V -V

       **xfs**___**growfs** is most often used in conjunction with logical volumes (see [**md**(4)](https://www.chedong.com/phpMan.php/man/md/4/markdown)  and  [**lvm**(8)](https://www.chedong.com/phpMan.php/man/lvm/8/markdown)  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.
