Management node personalization refers to the process of CFS applying a configuration to a management node after it is booted.
The same CFS configuration is used for post-boot personalization of master, storage, and worker management nodes. However, some individual parts of that configuration will only be applied to appropriate node types.
This document provides several common procedures which are performed during CSM install and upgrade and as operational tasks after the install or upgrade. Each procedure is described in its own section below.
This procedure describes how to re-run node personalization on management nodes even if no changes have been made to the configuration layers (such as a new layer, different playbook, or new commit made).
This procedures causes CFS to re-run personalization on management nodes by clearing the configuration state and error count on the management node components. This causes the CFS Batcher to reconfigure these components. See Configuration Management with the CFS Batcher for more information on the CFS Batcher.
This procedure has a scripted option and a manual option. Use the scripted option if possible.
The apply_csm_configuration.sh script can be used to easily clear the configuration state and
error count across all the management nodes at once. This causes CFS to reconfigure these
components. The script waits for all the management node components to complete their configuration
and reports a message indicating how many management nodes succeeded and how many failed their
configuration.
The script currently requires that we provide it with the name of the CFS configuration applied to the management nodes. If all management nodes do not use the same CFS configuration, it is best to use the Manual procedure to re-run node personalization on management nodes. The first step of this procedure checks whether all management nodes use the same CFS configuration.
(ncn-mw#) Get the CFS configuration applied to all management NCNs.
CFS_CONFIG_NAME="$(cray cfs components list --format json \
--ids "$(cray hsm state components list --role=management --format json \
| jq -r '.Components | map(.ID) | join(",")')" \
| jq -r 'map(.desiredConfig) | unique | first')"
echo "${CFS_CONFIG_NAME}" | xargs -n 1
If there is a single configuration applied to all management nodes, the output should look like this:
management-23.4.0
If there is more than one CFS configuration listed, use the Manual procedure to re-run node personalization on management nodes instead of the scripted procedure.
(ncn-mw#) Execute the script with the CFS_CONFIG_NAME variable set in the previous step.
/usr/share/doc/csm/scripts/operations/configuration/apply_csm_configuration.sh \
--no-config-change --config-name "${CFS_CONFIG_NAME}" --clear-state
Successful output will end with a message similar to the following:
Configuration complete. 9 component(s) completed successfully. 0 component(s) failed.
The number reported should match the number of management NCNs in the system.
This procedure manually clears the CFS configuration state and error count across all the management node components at once. This causes CFS to reconfigure these components.
(ncn-mw#) To re-run NCN personalization on all management NCNs at once, use the following loop:
FAILED="" ; COUNT=0 ; \
for xname in $(cray hsm state components list \
--role Management --type node \
--format json |
jq -r .Components[].ID)
do
echo "Clearing CFS state of ${xname}"
cray cfs components update --error-count 0 --state '[]' --format json "${xname}" && let COUNT+=1 || FAILED+=" ${xname}"
done ; \
echo "Cleared CFS state on ${COUNT} nodes" ; \
[[ -z ${FAILED} ]] && echo "No errors" || echo "ERROR: There were errors clearing the CFS state for the following nodes:${FAILED}"
This procedure describes how to re-run node personalization on a specific management node even if no changes have been made to the configuration layers (such as a new layer, different playbook, or new commit made).
This procedures causes CFS to re-run personalization on a management node by clearing the configuration state and error count on the management node component. This causes the CFS Batcher to reconfigure these components. See Configuration Management with the CFS Batcher for more information on the CFS Batcher.
(ncn#) Set XNAME to the xname of the management node which should be reconfigured.
Here is one way the xname can be obtained from the node to be reconfigured:
XNAME=$(cat /etc/cray/xname)
(ncn#) Clear the state and error count of the node using CFS.
cray cfs components update --error-count 0 --state '[]' --format json "${XNAME}"
