3.4. Increasing the Size of an XFS File System
An XFS file system may be grown while mounted using the
xfs_growfs /mount/point -D size
-D sizeoption grows the file system to the specified
size(expressed in file system blocks). Without the
xfs_growfswill grow the file system to the maximum size supported by the device.
Before growing an XFS file system with
-D size, ensure that the underlying block device is of an appropriate size to hold the file system later. Use the appropriate resizing methods for the affected block device.
While XFS file systems can be grown while mounted, their size cannot be reduced at all.
