Cluster status with 3 nodes

[KOSTAS TSIVERIOTIS]

Hello everybody,

I have a 3 node cluster with 1 node as master and 2 slave nodes.

When i check configuration/Cluster page, the master node 1, is always in state "active" and the two other nodes, node 2 and node 3, are always in state "syncing".

On dashboard pages, the master node 1 is diplaying different top receiver numbers different than node 2 and 3,
Node 2 and 3 display the same numbers.

Is this normal behaviour?

master ver Mail Gateway 5.1-4
node 1 ver Mail Gateway 5.1-4
node 2 ver Mail Gateway 5.2-1

Hello,

Can you check the status of pmgmirror and pmgtunnel of node 2 and 3
Also Check the status cluster synchronization

could you try to disable the razor2 checks - and see if this resolves the problem.

 

[KOSTAS TSIVERIOTIS]

can you give me some help on this?
How am I going to do it?

 

[Stoiko Ivanov]

for the razor2 checks it should be enough to go in the GUI:
'Configuration'->'Spam Detector'->'Options'-> 'Use Razor2 checks' -> disable

afterwards check the clustersync again

after razor checks disabled : syncing ok!

should i enable razor checks again?
