Are the client nodes running different versions of Lustre? The "get_param -R" option was just added in master, but since the test script is running only on the client node then it shouldn't need interop for this option?

In any case this is a harmless error in the test script, but it would be good to fix it in master before release so that it doesn't cause continuous interop test failures.

the "-R" option was added by LU-5030, landed on tag-2.8.50. need check the server version, if older than that, remove the option "-R"

This issue has been fixed by adding nodemap supportive check. cannot reproduce in master and b2_10
