No access to the cluster after rebooing the management Serverr

[ Edited ]



the manager is looking for an EXTERNEL DB, but the SetUp was INTERNAL.

No I do not know the settings for:


com.cloudera.cmf.db.setupType=INTERNAL (?)


Sep 28 14:44:03 SRV cloudera-scm-server-db[23593]: CM is using external DB. Failed to start embedded DB service, giving up
Sep 28 14:44:03 SRV su[23612]: pam_unix(su:session): session closed for user cloudera-scm
Sep 28 14:44:03 SRV systemd[1]: cloudera-scm-server-db.service: Control process exited, code=exited status=1
Sep 28 14:44:03 SRV systemd[1]: Failed to start LSB: Cloudera SCM Server's Embedded DB.
-- Subject: Unit cloudera-scm-server-db.service has failed


Can anyone help?





--- upgrade ---


the setup change from INT to EXT databse (but why?)


but there was a file with the values I needed.


Is there a good article how to setup a external postgres DB?

Re: No access to the cluster after rebooing the management Serverr

Hello @Vogone,


You have encountered a safeguard which should prevent the reconfiguring of your Cloudera Manager database from its previous setting due to having the embedded database package (cloudera-manager-server-db-2)


First, check to see if your current is correct:

cat /etc/cloudera-scm-server/


If it is not correct, then check for other files in /etc/cloudera-scm-server/ directory to see if any are correct.

copy the correct one to if the current one is not correct.


If you have configured Cloudera Manager to use a non-embedded database (as it seems you have not), then remove the "cloudera-manager-server-db-2" package from your Cloudera Manager host.  When you reboot, it is configured to start.  When cloudera-manager-server-db-2 package starts (cloudera-scm-server-db) it will attempt to configure your to connect to an "embedded" postgres db.


Once you have the correct file configured and the cloudera-manager-server-db-2 package is removed, start Cloudera Manager.
