The `OCF_CHECK_LEVEL=20` attribute is added to the monitor operation, so that monitor operations perform a read/write test on the file system. Without this attribute, the monitor operation only verifies that the file system is mounted. This can be a problem because when connectivity is lost, the file system might remain mounted, despite being inaccessible.

The `on-fail=fence` attribute is also added to the monitor operation. With this option, if the monitor operation fails on a node, that node is immediately fenced. Without this option, the default behavior is to stop all resources that depend on the failed resource, then restart the failed resource, and then start all the resources that depend on the failed resource. Not only can this behavior take a long time when an SAP HANA resource depends on the failed resource, but it also can fail altogether. The SAP HANA resource can't stop successfully, if the NFS share holding the HANA binaries is inaccessible.
