This test started failing in inerop testing with 2.7.x servers before December 2017; this is as far back as I’ve looked for this failure. All failures are 2.11.0, 2.10.x clients with 2.7.x servers. I don’t see this failure with 2.12 nor master probably because we don’t interop test these releases with 2.7.x.

Looking at several of these failure for b2_10 client and 2.7.x servers at there are no errors in any of the dmesg nor console logs for any nodes.

There are several failures for a variety of different Lustre versions:
