Troubleshooting Ops Manager on GCP
Page last updated:
Warning: VMware Tanzu Application Service for VMs (TAS for VMs) v2.9 is no longer supported because it has reached the End of General Support (EOGS) phase as defined by the Support Lifecycle Policy. To stay up to date with the latest software and security updates, upgrade to a supported version.
This topic describes how to troubleshoot known issues when deploying Ops Manager on Google Cloud Platform (GCP).
Users may be unable to connect to applications running on Ops Manager using SSO for VMware Tanzu.
SSO for VMware Tanzu does not support multi-subnets.
Ensure that you have configured only one subnet. See Preparing to Deploy Ops Manager on GCP Manually.
Uploading the VMware Tanzu Application Service for VMs (TAS for VMs) tile causes the Ops Manager Rails application to crash.
In compressed format, the TAS for VMs tile is 5 GB in size. However, when uncompressed during installation, the TAS for VMs tile requires additional disk space that can exhaust the space allocated to the boot disk.
Ensure that the boot disk is allocated at least 50 GB of space. See Create the Ops Manager VM Instance in Deploying Ops Manager on GCP Manually.
During installation of the TAS for VMs tile, the replication-canary job fails to start. The error reported in the installation log resembles the following:
Started updating job mysql_monitor > mysql_monitor/0 (48e7ec82-3cdf-41af-9d0f-90d1f12683c8) (canary). Failed: 'mysql_monitor/0 (48e7ec82-3cdf-41af-9d0f-90d1f12683c8)' is not running after update. Review logs for failed jobs: replication-canary (00:05:13) Error 400007: 'mysql_monitor/0 (48e7ec82-3cdf-41af-9d0f-90d1f12683c8)' is not running after update. Review logs for failed jobs: replication-canary
This error can appear as a result of incorrect configuration of network traffic and missed communication between the Gorouter and a load balancer.
Make sure you have selected the Forward SSL to TAS for VMs Router option in your TAS for VMs Network Configuration.
Verify that you have configured the firewall rules properly and that TCP ports
8080are accessible on your GCP load balancers. See Create Firewall Rules for the Network in Preparing to Deploy Ops Manager on GCP Manually.
Verify that you have configured the proper SSL certificates on your HTTP(S) load balancer in GCP. See Create HTTP Load Balancer in Preparing to Deploy Ops Manager on GCP Manually.
If necessary, re-upload a new certificate and update any required SSL Certificate and SSH Key fields in your TAS for VMs Network Configuration.
Upgrade issues can be caused when the external database user used for the network policy DB is given insufficient permissions. To avoid this upgrade issue, ensure that the networkpolicyserver database user has the
ALL PRIVILEGES permission.
