Elasticsearch Storage Issues

Hot/Warm Node Parity

A way of increasing the storage space for either Hot or Warm nodes is to increase them. If increasing one then the other must be equal as well, for example if upping the Hot nodes to 20 Warm should be upped to 20 as well.

The number of shards and the nodes should be increased by a multiple of the index with the largest number of shards, further information.

Manually migrating failed indexes

It may be necessary to migrate indexes manually. The process for this is:

  1. Navigate to “Policy managed indices”
  2. Find Failed to start **** migration
  3. Copy the index name
  4. Search “Warm” indexes and get index size
  5. Search “Cold” indexes and get index size
  6. If the “Cold” index size is smaller than “Warm” then it can be deleted
  7. Delete the index via the devtools DELETE _cold/live_kubernetes_ingress-2024.07.13
  8. Click retry policy
