similar to the following appears in the
/var/log/fdm.log
file.
[ClusterManagerImpl::ConnectToMaster] Couldn't connect to master
N7Vmacore16TimeoutExceptionE(Operation timed out)
[ClusterManagerImpl::AddBadIP] IP 10.x.x.x marked bad for reason Unreachable IP
[ClusterElection::ChangeState] SlaveConnecting => Startup : SlaveConnectingStateFunc
[ClusterManagerImpl::IsBadIP] 10.x.x.x is bad ip
The following situations are observed as a result of the timeout:
• High Availability configuration fails.
• High Availability cannot be configured on a cluster.
• High Availability configuration completes on the master but fails on all slaves.
Cause
This issue occurs if Jumbo Frames are enabled on the host Management Network (the VMkernel
port used for host management) and the network configuration is not configured for jumbo frames.
This issue is resolved by ensuring that the vSwitch and Management Network MTU values are
configured to 1500.
Solution
1. Right-click the cluster host in vSphere Client.
2. Click the
Configuration
tab.
3. Click
Networking
.
4. Click
