Troubleshooting Calamari is sometimes very tricky. In this recipe, I have collected some recipes that will help you troubleshoot your Calamari environment.
- Check if the Calamari server, that is, the salt-master, could reach salt-minions:
# salt '*' test.ping - Check if salt-master can query the Ceph cluster and get cluster information:
# salt '*' ceph.get_heartbeats output - Check if the salt-minion node (Ceph cluster node) could reach the salt-master:
# salt-minion -l debug - Salt-minion throws an error, The Salt Master server's public key did not authenticate!, under the
salt-minionlog file, that is,/var/log/salt.
- To solve this problem, we need to delete the
minionsalt-key as well as the master public key and recreate both of them using the following commands:# rm -rf /etc/salt/pki/minion/minion_master.pub # systemctl stop salt-minion
Now, perform the following set of steps:
- On salt-master, delete the minion key:
# salt-key -L # slat-key -D <minion name>
- Start the
salt-minionservice:# systemctl start salt-minion - On salt-master, accept the new key for minion:
# salt-key -L # salt-key -A
- Finally, on salt-minion, use
# salt-minion -land make sure you do not get this error again.
- On salt-master, delete the minion key:
- Execute the
calamari-ctl initializecommand that will throw the could not connect to server: Connection refused error as follows:
Then, perform the set of steps mentioned as follows:
- First, check if the postgres services are running:
# systemctl status postgres - Log in to postgres and check whether the Calamari database exists or not:
# sudo -u postgres psql List postgres databases # l
- You might see that there is no database called
calamari; now you should invokesaltto create acalamariuser and database in postgres:# salt-call --local state.template /opt/calamari/salt-local/postgres.sls - Finally, re-run
# calamari-ctl initialize; it should work this time.
- First, check if the postgres services are running:
- The
calamari-ctl initializecommand line fails to throw the Updating already connected nodes. failed with rc=2 error, as seen in the following screenshot:
- To fix this error, edit the
/opt/calamari/venv/lib/python2.7/site-packages/calamari_cthulhu-0.1-py2.7.egg/cthulhu/calamari_ctl.pyfile, and comment out line 255, which saysupdate_connected_minions().
