• Type: Bug

Environment

RHEL8.3 server

• Severity: 3

Description

The parallel-scale-nfsv4 test suite is failing in NFS setup and, thus, no tests are run. We are seeing this for RHEL8.3 servers.

Looking at a recent failure at https://testing.whamcloud.com/test_sets/d76032dc-6074-406f-824c-a7f3676496cb, we see

CMD: trevis-202vm4 { [[ -e /etc/SuSE-release ]] &&
				 service nfsserver restart; } ||
				 service nfs restart ||
				 service nfs-server restart
trevis-202vm4: Redirecting to /bin/systemctl restart nfs.service
trevis-202vm4: Failed to restart nfs.service: Unit nfs.service not found.

  Trace dump:
  = /usr/lib64/lustre/tests/test-framework.sh:6273:error()
  = /usr/lib64/lustre/tests/parallel-scale-nfs.sh:68:main()

When we see this failure, so far, it is when node-provisioning/lustre-initialization takes place right before parallel-scale-nfsv4 is run.

Comments

[Andreas Dilger]

Have the NFS tools RPMs been installed?

[James Nunez (Inactive)]

parallel-scale-nfsv3 runs before parallel-scale-nfsv4, actually parallel-scale-nfsv3 runs and hangs which causes the cluster to run node-provisioning/lustre-initialization, and parallel-scale-nfsv3 does start the NFS servers.

Looking at the suite_log for parallel-scale-nfsv3, at https://testing.whamcloud.com/test_sets/bc5183ad-2cad-4b97-aba4-604b73b9765f, the NFS server starts

Mounting NFS clients (version 3)...

Looking at the MDS (vm4) console log, we see acknowledgment from NFSD before parallel-scale-nfsv3 starts running tests

So, the NFS RPMs were loaded on the servers.
