+# XFS
+XFS is a high-performance, scalable file system designed for Unix-like operating systems. It was originally developed by Silicon Graphics, Inc. (SGI) and later open-sourced. XFS is known for its robustness, advanced features, and suitability for large-scale storage environments.
+
+## File System Creation and Management
+
+Creating an XFS file system can be done using the mkfs.xfs command:
+```shell
+mkfs.xfs /dev/sdX
+```
+
+To mount an XFS file system, use the mount command:
+```shell
+mount -t xfs /dev/sdX /mnt/point
+```
+
+Grow the filesystem:
+```shell
+xfs_growfs /mnt
+```
+
+Get information on filesystem:
+```shell
+xfs_info /mnt
+```
