the problem is in the test1 of connectathon of parallel-scale.sh, and there is a Segmentation fault in this test.
but it seems to be not related to Lustre for it occurs on the NFS4 client, and there are something confused in the logs of the test,
the nodes in this test is fat-intel-1(MDT), fat-intel-2(OST), Client(client-18), but the NFS4 server is at client-5 (10.10.4.5)

Hi Sarah,
Is there a Lustre client mounted on client-5 and export the Lustre directory via NFS4?

[Sarah Liu]

Hi Sarah,
Is there a Lustre client mounted on client-5 and export the Lustre directory via NFS4

yes. since I ran those tests on client-18 which is nfs client, I thought that was the reason client-15 was not listed in the node list

[Hongchao Zhang]

the logs in client-5 (the nfs server exporting Lustre client) are needed for this issue, for the logs in client-18 can't give any trace except
the "Segmentation fault". Furthermore, it's only related to test tools of NFS4, not Lustre.

[Sarah Liu]

please find the attached for logs from NFS server(lustre client)

Oleg reports that all his NFS tests now pass cleanly. Could you please confirm whether this issue still exists after build 63 becomes available next week?

Thanks

Peter

[Sarah Liu]

sure, will verify all nfs tests after the new build is available.

[Peter Jones]

This issue did not occur during testing for build 63
