OK, seems that this works now.
A couple of questions:
- What do you think, are all these options necessary for Kafka?
- You wrote that there have to be kind of application profiles. So to find out, which set of options work is currently a matter of testing (and hope)? Or are there any experiences for MongoDB / ProstgreSQL / Zookeeper etc.?
- I am using Heketi and Dynamik Storage Provisioning together with Kubernetes. Can I set this volume options somehow by default or by volume plugin?
Thanks for you help... really appreciated.. Christopher

Looks like a problem with caching. Can you please try by disabling all performance translators? The following configuration commands would disable performance translators in the gluster client stack:gluster volume set <volname> performance.quick-read offgluster volume set <volname> performance.io-cache offgluster volume set <volname> performance.write-behind offgluster volume set <volname> performance.stat-prefetch offgluster volume set <volname> performance.read-ahead offgluster volume set <volname> performance.readdir-ahead offgluster volume set <volname> performance.open-behind offgluster volume set <volname> performance.client-io-threads offThanks,VijayOn Mon, May 22, 2017 at 9:46 AM, Christopher Schmidt <fakod666@xxxxxxxxx> wrote:Hi all,has anyone ever successfully deployed a Kafka (Cluster) on GlusterFS volumes?I my case it's a Kafka Kubernetes-StatefulSet and a Heketi GlusterFS.Needless to say that I am getting a lot of filesystem related exceptions like this one:Failed to read `log header` from file channel `sun.nio.ch.FileChannelImpl@67afa54a`.
