Hi,
we have cluster with 2 nodes. Every node has set data_type
attribute.
One node has low disk watermark exceed.
We prepared ILM policy to keep indices on one node for some time and after move it to another.
Rarely I move some indices manually to another node by set index routing.allocation.require.data_type
setting.
Few days ago one of node filled up disk because moving indices to another node stops working. When I manually set routing.allocation.require.data_type
to value of second node data_type parameter nothing happens (I can't see any relocating shards in _cat/shards
results. cluster/allocation/explain
also doesn't show anything).
Few months ago I move indices this way without problems.
All (production) indices has 0 replicas so low disk watermark should not be a problem.
Have you any idea why indices doesn't move to another node?
Elastic version: 6.8.13
Thank you.
