I am confused over persistent storage for logging (elasticsearch).
The latest advanced installer docs [1] specifically describes how to
define using NFS for persistent storage, but the docs for "aggregating
container logs" [2] says that NFS should not be used (except in one
particular scenario) and seems to suggest that the only really
suitable scenario is to use a volume (disk) directly mounted to each
logging node.
Could someone clarify the situtation?
Elasticsearch says do not use NFS.
https://www.elastic.co/guide/en/elasticsearch/guide/2.x/indexing-performance.html#_storage
We should make that clear in the docs.
Please file a doc bug.
