Simon Willnauer 6e5cc424a8 Switch indices read-only if a node runs out of disk space (#25541) ... Today when we run out of disk all kinds of crazy things can happen and nodes are becoming hard to maintain once out of disk is hit. While we try to move shards away if we hit watermarks this might not be possible in many situations. Based on the discussion in #24299 this change monitors disk utilization and adds a flood-stage watermark that causes all indices that are allocated on a node hitting the flood-stage mark to be switched read-only (with the option to be deleted). This allows users to react on the low disk situation while subsequent write requests will be rejected. Users can switch individual indices read-write once the situation is sorted out. There is no automatic read-write switch once the node has enough space. This requires user interaction. The flood-stage watermark is set to `95%` utilization by default. Closes #24299		2017-07-05 22:18:23 +02:00
