Hi, Tristan Tarrant

If I will use any JDBC cache store then I will create single point of failure in my configuration. Plus I should spend additional hardware for running some database (processors and RAM). It isn't good.

My current Infinispan cluster configuration may be isn't beatyful, but it works:

- each node have own file store (LevelDB) in separate disk folder

- all nodes synchronized via JGroups

Good sides of this solution:

- I spend only disk space, but today this isn't expensive

- Each node of my configuration is exactly same as others. I can copy it, start or stops in any time.

Best regards,

Eugeny

Hi, Wolf-Dieter Fink !

Thanks for answer. It has very useful information for me!

> - node crashed >= numOwner for DIST caches and you loose data

I have no distributed caches in my configuration, I use only replicated caches.

> - complete cluster shutdown must be done carefully to not loose data or have stale data / inconsistent cluster nodes

Thanks. I have configured persistency of global state now.  All my cluster nodes uses same directory for it:

        <global-state>

            <persistent-location path="/mnt/shared/cache_global" />

            <temporary-location path="/mnt/shared/cache_global/tmp"/>               

        </global-state>

Is it correct? In documentation I can't find exact explanation about it. I think that global state must be shared between all nodes.

Best regards,

Eugeny
