HA rscync error on active/passive HA Cluster

hi guys,

ugh, with 9.5 sophos made a bad job, once again.

Since upgrading SG330 active/passive cluster to 9.5  (now 9.502-4) we had several problems. SSO didn´t update the group entries from AD. (i.e. group members in "internet allow" AD group won´t be updated, so that users new to this group can´t use internet, also users removed from group are still able to use)

Second, the db syncing of HA cluster seems to fail. Even the Status Tab in HA shows Master als Active and Slave as Ready, the HA log produces errors  every 10 seconds

2017:08:14-09:00:39 xxxx-01-2 repctl[3738]: [i] execute(1768): Is server running?

 

and every 55 minutes we got message from alerting system:

HA SELFMON WARN: Restarting repctl for SLAVE(ACTIVE)

 

Any ideas? Exept of rebuild postgresql db´s or releasing HA status and firmware reset of Slave and rebuild HA.

  • Hi Thomas,

    Daniel has a potential suggestion to your question. It could be that the slave's partition filled up. Also, check if you see any log lines similar to,

    "[user:notice] cluster_sync[1590]: rsync: write failed on "/var/up2date/aptp/u2d-aptp-9.23906.tgz.gpg" (in cluster_sync): No space left on device (28)

    You can check in the fallback.log, execute:

    fallback.log | grep no space  

    If that doesn't help, rebuild postgres and that should resolve the issue.

    Thanks

  • Hi,

     

    thx for information.

    As written before, it´s not  problem with "no space". All partitions, even on the slave, have enough space.

    And i´ve asked for a  solution without breaking up the cluster nor rebuilding the postgres.

     

    But if this is the only way, i´ve to do so.

  • Hi

     

    Did you manage to solve this issue?

    I have no exact the same situation and also do not want to break the cluster. 

     

    Regards

  • Hi aedii,

     

    it´s long ago, but at least we broke up the cluster, reinitialised the slave machine an than rejoined to the cluster.

    perhaps in the meantime, there are better soltions...?

  • Hi tkaufi

    Thanks for your reply.

    I rebuilt the Postgre DB on both machines.

     

    I connected to both machines with ssh and then issued these commands:

    - killall repctl

    - /etc/init.d/postgresql92 rebuild

    - repctl

    - reboot slave node

     

    and then it synced again without breaking the cluster, but lost the DB.
