Lustre-2.3 server does not support initial OI scrub, so test_1a (triggered by Lustre-2.4 client) cannot work. So please ignore sanity-scrub test_1a for the interoperability between Lustre-2.4 client and Lustre-2.3 server.

[Andreas Dilger]

We want the tests to always pass, rather than have false errors that need to be investigated every time. If sanity-scrub test_1a() is known not to work with 2.3.0 servers, then it should be skipped from within the test_1a() script by checking the server version.
