TripleO has several THT parameters [1] that control whether an NFS or Netapp NFS cinder backend supports a Netapp feature known as "NAS secure." The feature is largely broken, and users that enable it encounter a number of problems (see [2]). TripleO disables the feature by default, but our docs should explicitly state the feature is not supported in OSP (see bug #1794581 comment #5). [1] THT parameters are: CinderNetappNasSecureFileOperations CinderNetappNasSecureFilePermissions CinderNasSecureFileOperations CinderNasSecureFilePermissions [2] https://bugzilla.redhat.com/buglist.cgi?bug_status=__closed__&f1=cf_devel_whiteboard&list_id=10803419&o1=allwords&query_format=advanced&v1=cinder_nas_secure
I provided feedback on the doc changes in the gitlab PR.
