Chapter 13. Increasing the size of an XFS file system

Prerequisites

• 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.

Procedure

• While the XFS file system is mounted, use the xfs_growfs utility to increase its size:

  # xfs_growfs file-system -D new-size

  Copy to Clipboard Toggle word wrap
  • Replace file-system with the mount point of the XFS file system.

  • With the -D option, 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 utility:

    # xfs_info block-device
    
    ...
    data     =              bsize=4096
    ...

    Copy to Clipboard Toggle word wrap

  • Without the -D option, xfs_growfs grows the file system to the maximum size supported by the underlying device.

    For more information, see the xfs_growfs(8) man page on your system.
