Assumptions before running this test:

Ansible scripts are run successfully which configures iSCSI on selected worker nodes and labels them with 'iscsi=sbps'. Goss tests use this label as identification of nodes on which this test has to run.

SBPS GOSS Frame work:

SBPS GOSS tests run some of the sanity tests for SBPS solution and these tests run on worker node(s) where iSCSI is configured and the SBPS Marshal agent is running. Bash script 'https://github.com/Cray-HPE/csm-testing/blob/release/1.6/goss-testing/scripts/iscsi_sbps_sanity.sh' does the below mentioned sanity checksfor SBPS:

  • Verify SPBS Agent is running (systemd service)
  • Verify LIO target is active
  • Verify TCP service probes complete against all active portals (iSCSI)
  • Verify DNS SRV and A records exist for the worker respective of the iSCSI portals
  • Verify the mapping between DNS A records and host iscsi portals

The goss script which determines on which nodes the script 'iscsi_sbps_sanity.sh' has to run is determined by 'https://github.com/Cray-HPE/csm-testing/blob/release/1.6/goss-testing/tests/ncn/goss-validate-iscsi-sbps-config.yaml'. Once the 'csm-testing' package is installed, GOSS frame work takes care of placing these scripts in required directory location on test system(s), here it will be on worker nodes. Please ensure 'iscsi_sbps_sanity.sh' is placed under /opt/cray/tests/install/ncn/scripts/ directory and 'https://github.com/Cray-HPE/csm-testing/blob/release/1.6/goss-testing/tests/ncn/goss-validate-iscsi-sbps-config.yaml' is placed under /opt/cray/tests/install/ncn/tests/ directory. And also, ensure an entry for goss-validate-iscsi-sbps-config.yaml is present in /opt/cray/tests/install/ncn/suites/ncn-healthcheck-worker.yaml as this SBPS sanity test will be run during ncn-health checks.

Steps to run:

Ensure 'goss-servers' systemd service is running on all the nodes (master and worker): If not, restart the goss-server on all the worker nodes configured with iSCSI.

systemctl restart goss-servers.service
systemctl status goss-servers.service

Expected output:

    goss-servers.service - goss-servers
     Loaded: loaded (/etc/systemd/system/goss-servers.service; disabled; vendor preset: disabled)
    Active: active (running) since Tue 2024-01-16 18:47:59 UTC; 1 day 18h ago
    Main PID: 1630316 (bash)
    Tasks: 682
    CGroup: /system.slice/goss-servers.service

Two ways to run the goss tests:

Method #1: Run the below script from master/pit node

/opt/cray/tests/install/ncn/automated/ncn-healthcheck-worker

This will run the test on all the corresponding worker nodes which are configured with iSCSI.

Method #2: Run on Individual node (worker):

Set the below GOSS environment variable

export GOSS_BASE=/opt/cray/tests/install/ncn

Then run the below command:

goss -g /opt/cray/tests/install/ncn/tests/goss-validate-iscsi-sbps-config.yaml validate

This command will run the test on the individual node on which this was run where iSCSI is confgured.
