Running Solr 7.2 in SolrCloud mode with 5 Linux VMs. Each VM was a single shard, no replication. Single Zookeeper instance running on the same VM as one of the Solr instances.
IT was making changes, and 2 of the VMs won't reboot (including the VM where Zookeeper is installed). There was a dedicated drive which Solr (and Zookeeper for the one node) where installed on, and a dedicated drive where the Solr indexes were created. They believe the drives are still good. Their plan is to create 2 new VMs and attach the drives from the old VMs to them. However the IP addresses of the new VMs will be different. In the solr.in.sh I had set the SOLR_HOST entry to the IP address of the VM. Is this just an arbitrary name? Will Zookeeper still recognize the Solr instance if the SOLR_HOST entry doesn't match the IP address. Obviously I will need to adjust the ZK_HOST entries on all nodes to reflect the new IP address of the VMs. But will that be sufficient? Appreciate any guidance. Thanks - Andy -
