ElastiSearch Supports GlusterFS and Rook Storage System?

[DavidTurner]

We don't run any tests against either of those systems, and generally recommend to use local storage instead of network-attached storage for performance reasons. Past versions of GlusterFS are known to cause corruptions in Elasticsearch indices - for example:

Underlying file changed by an external force

The first two Google hits for elasticsearch glusterfs lead to two serious-looking open GlusterFS issues that Elasticsearch triggers: https://bugzilla.redhat.com/show_bug.cgi?id=1390050 https://bugzilla.redhat.com/show_bug.cgi?id=1379568 This may be one of them, or may be something else, but it seems worth rethinking your setup. I don't think so. Both of the times I quoted are in UTC (note the trailing Z) and differ by 28 seconds, so it seems unlikely to be a timezone issue.
