9:40 p.m.
Strangely, it seems to have fixed itself over the weekend. I came to look at it this
morning and the new node successfully retrieved the initial state data. I've not made
any changes to configuration etc.
I'd still like to know why it was happening and how to prevent it though.

No, I just start up keycloak and run standalone ha. There's no mention of that
property in the keycloak docs about clustering

Matt,
How did you add your new node?
Have you defined the jboss.node.name<http://jboss.node.name> property in your new
node?

We're running keycloak clustered with standalone-ha.xml, and it's been working
fine.
We changed the 'owners' of the distributed caches for session, loginFailures etc
to 2 so that it will distribute those caches across the 2 nodes in the cluster.
Now, when I remove a node and add a new node, the new node fails to start some of the
services, due to:
org.infinispan.commons.CacheException: Initial state transfer timed out for cache sessions
on xxxx
Is this because it's actually taking too long to fetch the initial cache data from the
other node? Is it due to the size of the cache, or some other issue?
What can I do to address this so that I can add the node back into the cluster?
I'm not experienced at all in infinispan or jgroups, so any pointers on how to query
the servers to see whats in the caches, and how to see what's actually happening will
be appreciated!
Thanks
Matt
