• How to have highly available Moodle in Kubernetes?

  Want to set up highly available Moodle in K8s (on-prem). I'm using Bitnami Moodle with helm charts.

  After a successful Moodle installation, it becomes work. But when a K8s node down, Moodle web page displays/reverts/redirects to the Moodle installation web page. It's like a loop.

  Persistence storage is rook-ceph. Moodle PVC is ReadriteMany where Mysql is ReadWriteOnce.

  The following command was used to deploy Moodle.

  helm install moodle --set global.storageClass=rook-cephfs,replicaCount=3,persistence.accessMode=ReadWriteMany,allowEmptyPassword=false,moodlePassword=Moodle123,mariadb.architecture=replication bitnami/moodle
  

  Any help on this is appreciated.

  Thanks.
• High-Availability not working in Hadoop cluster

  I am trying to move my non-HA namenode to HA. After setting up all the configurations for JournalNode by following the Apache Hadoop documentation, I was able to bring the namenodes up. However, the namenodes are crashing immediately and throwing the follwing error.

  ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode. java.io.IOException: There appears to be a gap in the edit log. We expected txid 43891997, but got txid 45321534.

  I tried to recover the edit logs, initialize the shared edits etc., but nothing works. I am not sure how to fix this problem without formatting namenode since I do not want to loose any data.

  Any help is greatly appreciated. Thanking in advance.
• Apache Kafka Consume from Slave/ISR node

  I understand the concept of master/slave and data replication in Kafka, but i don't understand why consumers and producers will always be routed to a master node when writing/reading from a partition instead of being able to read from any ISR (in-sync replica)/slave.

  The way i think about it, if all consumers are redirected to one single master node, then more hardware is required to handle read/write operations from large consumer groups/producers.

  Is it possible to read and write in slave nodes or the consumers/producers will always reach out to the master node of that partition?
