From this I work out that I should be using about 10Gx2000 = 20TB (I know, x1.5 to take into account ES indexing/etc) before the deletion of old indexes kicks in, and on top of that the replicas = 2 should mean this is using 40TB (or is it 60TB?) of diskspace aggregated on the cluster members…
But on this 5-node ES cluster, I’m only seeing 5x1.4TB of diskspace in use. It’s ‘steady state’ - I’m seeing the deletion rotation policy triggering in the logs - so obviously I’ve screwed something up. Any ideas?
But thanks - you’ve answered my question. I was unaware of this change. I used to have elasticsearch_max_number_of_indices set to 800 - but increased it in the config - but obviously that doesn’t work any more. But looking in the ‘System->Indices’ area, I see it’s still set to 800. Now I know what to do
