This article introduces the relevant knowledge of "Linux extends the XFS file system to fully use the extra space method". In the actual case operation, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Linux extends the XFS file system steps:

XFS is an open source (GPL) journaling file system originally developed by Silicon Valley Graphics (SGI) and is now supported by most Linux distributions. In fact, XFS has been adopted by the latest CentOS/RHEL 7 as its default file system. Among its many features, it includes the feature of "resizing online", which allows the existing XFS file system to be extended when it is already mounted. However, there is no support for XFS file system reduction.

To extend an existing XFS file system, you can use the command line tool xfs_growfs, which is available by default on most Linux distributions. Because XFS supports online resizing, the destination file system can be mounted or unmounted.

The basic usage of xfs_growfs is shown below:

As a target XFS file system extension, you can specify mount points, disk partitions, or logical volumes (when using LVM), and use the number of blocks to specify the size of the new XFS file system. You can use the xfs_info command line tool to check the block size and number:

To extend the XFS file to 1986208:

If you do not use the "- D" option to specify the size, xfs_growfs will automatically extend the XFS file system to the maximum available size.

Note that when you extend an existing XFS file system, you must be prepared to add space for XFS file system extension in advance. While this is obvious, there is nothing xfsgrowfs can do if there is no free space on the partition or disk volume on which it is located. At the same time, if you try to extend the size of the XFS file system to more than the size of the disk partition or volume, xfsgrowfs will fail.
