The XFS file system provides the best performance for both SAP HANA data and log block devices.
To format a block device with the XFS file system, run the following command on the SAP HANA node:
$ mkfs.xfs /dev/mapper/3600601600a503e00690f195784759af8
Note: Run this command for all block devices.
If for some reason you must expand a file system, run the xfs_growfs command on the Linux host after you expand the volume on the Unity array.
