pf9configure.log

TASK [pf9-configure : Wait for resmgr service] *********************************
 2025-02-03T23:32:44.466-0800 info INFO:pf9deploy.server.util.shell:| Tuesday 04 February 2025  07:02:42 +0000 (0:00:01.849)       0:12:17.577 ******

Environment

• Platform9 Edge Cloud - v5.3.0 and Higher

Diagnostic Steps:

• Check and identify if the logs of service pf9-resmgr inside the duVM are as below (use as String Search reference):

pf9-resmgr.service

Feb 03 09:03:13 airctl-1.pf9.localnet pf9-resmgr[3472]: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 4: invalid continuation byte

Resolution

• Rollback the environment to the latest available backup that is taken during upgrade start.
• Identify the bbslave password in the file .airctl/mongo/secrets.json present on the DU Host.
• On the DU Host, perform the below commands sequentially.

DU Host

# docker start airctl-mongo
# docker exec -it airctl-mongo bash

bash$ mongo
    > use pf9
    > db.secrets.find().pretty()

• The above command prints out all the secrets in the mongoDB; identify the secret with tag as below: airctl-1-pf9-localnet-rabbit_bbslave_password
• Confirm the password present for this record in mongoDB is the same as seen in the file .airctl/mongo/secrets.json
• If it is not the same, change the mongoDB record with the below command:

Mongo Shell

db.secrets.updateOne({"tag":"airctl-1-pf9-localnet-rabbit_bbslave_password"}, {$set: {"record": {"HYAT!": "<password present in secrets.json file>", "binary": false}}})

• Exit the mongoDB shell.
• On the DU Host run the below command:

DU Host

# /opt/pf9/airctl/airctl  advanced-du save-mongo --config /opt/pf9/airctl/conf/airctl-config.yaml

• Attempt the Upgrade again.
