Hi, I have a confusion regarding the setting cluster.routing.allocation.disk.include\_relocations =\> Defaults to true, which means that Elasticsearch will take into account shards that are currently being relocated to the target node when computing a node’s disk usage. Taking relocating shards' sizes into account may, however, mean that the disk usage for a node is incorrectly estimated on the high side, since the relocation could be 90% complete and a recently retrieved disk usage would include the total size of the relocating shard as well as the space already used by the running relocation. So if I have 100 gb disk and I have set the high watermark as 90% which means after 90GB shards will be reallocated. Now let us say the current disk usage is 80GB and I give a command to migrate a 7GB shard to this node. When 5GB of the shard is transferred, the disk usage will be calculated as follows: 80GB (Existing) + 5GB(transferred) + 7GB (entire size of the shard being transferred) = 92GB. Does that mean at this stage ES will start relocating some other index from this shard, since it has breached the high watermark? ---

Anyone who'll be able to help in clearing this? ---
