As a system administrator, you can increase the size of an XFS file system to make a complete use of a larger storage capacity.
It is not currently possible to decrease the size of XFS file systems.
20.1. Increasing the size of an XFS file system with xfs_growfs
This procedure describes how to grow an XFS file system using the
- Ensure that the underlying block device is of an appropriate size to hold the resized file system later. Use the appropriate resizing methods for the affected block device.
- Mount the XFS file system.
While the XFS file system is mounted, use the
xfs_growfsutility to increase its size:
# xfs_growfs file-system -D new-size
- Replace file-system with the mount point of the XFS file system.
-Doption, replace new-size with the desired new size of the file system specified in the number of file system blocks.
To find out the block size in kB of a given XFS file system, use the
# xfs_info block-device ... data = bsize=4096 ...
xfs_growfsgrows the file system to the maximum size supported by the underlying device.
