Hi,
I too am receiving this error like others. I know that I can fix it via the _settings endpoint:
PUT /_all/_settings {"index.blocks.read_only_allow_delete": false}
But, I have not run out of diskspace. I have lots of space available. The message clearly says: too many requests. But actually, there were not. When I cleared the flag, the problem did not repeat. UPDATE: the problem repeats. All indexes seem to be with a problem now. It is a cluster problem as the exception below shows
UPDATE 2: I currently configured the watermarks: https://stackoverflow.com/a/34221506/3208034. still not sure why there are TOO_MANY_REQUESTS thrown and why the watermarks shout when there plenty of room in the disk.
How can I troubleshoot this? Is there some kind of threshold or configuration where I can review and modify this?
Partial stacktrace:
org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=cluster_block_exception, reason=index [myindex] blocked by: [TOO_MANY_REQUESTS/12/index read-only / allow delete (api)];]
