searchguard index not replicated on every node due to node attribute awareness

Search Guard
1

My questions deal with Searchguard and the replication factor.

I’m in a situation where I don’t manage to replicate the searchguard index on every nodes due to node attributes awareness at cluster level (see https://discuss.elastic.co/t/disable-cluster-routing-allocation-same-shard-host-true-for-a-particular-index/164172 ).

AFAIK, it’s impossible to disable “cluster.routing.allocation.awareness.attributes” parameter for a specific index. (but I may be mistaken…)

So, I have to reduce the replication factor of the searchguard index manually ; otherwise, the searchguard index state, and so the cluster state, will stay YELLOW.

Questions:

  • does the non-allocation of the searchguard index on each node represent a serious performance issue?
  • how do you handle this kind of situation?
    Any solution or suggestion will be appreciated.

Thanks!

  • does the non-allocation of the searchguard index on each node represent a serious performance issue?

no

  • how do you handle this kind of situation?

To solve this disable the auto-expand replicas feature of the searchguard index and set the number of replicas manually.
You can also keep the auto-expand replicas feature and set it to "0-n" where n is the number of datanodes-2.
