====== xfs_growfs ======

  * [[XFS]]
  * [[mkfs.xfs]]

Use ''xfs_growfs'' to grow an already mounted XFS device.

=== Initialize specific size ===

Start off with a size of 1 GB:

<code>
mkfs.xfs -d name=/dev/sda,size=1g
</code>

Mount the device as normal:

<code>
mount /dev/sda /mnt/xfs
</code>

Verify everything:

<code>
xfs_info /dev/sda
</code>

=== Grow to a specific size ===

Double the disk size to 2 GB, using the # blocks as a reference (262144):

<code>
xfs_growfs -D 524288 /mnt/xfs
</code>

data blocks changed from 262144 to 524288

=== Use all available space ===

With no arguments, ''xfs_growfs'' will use all the available remaining space allocated to it.

<code>
xfs_growfs /mnt/xfs
</code>
