Description of problem: General Git operations have the potential to create hundreds of disk lookups, what has a negative impact on performance on GlusterFS. GlusterFS team has provided a negative lookup caching feature that can be enabled as a mount parameter. We need that OpenShift supports mount parameters for GlusterFS storage. Additional info: https://issues.jboss.org/browse/RHDM-71
It looks like this has been done upstream in Kube https://bugzilla.redhat.com/show_bug.cgi?id=1535041 Next step is to verify if storage plugins need implement this as well.
Mount options are implemented in OpenShift 3.6 as alpha / technology preview https://docs.openshift.com/container-platform/3.7/architecture/additional_concepts/storage.html#pv-mount-options In 3.8, it will be possible to set them in a storage class so all dynamically provisioned volumes will have the right mount options. Is there anything missing?
I'm closing this given this is tracked through BZ 1693084. We should have a different bug in OCS to allow the group-nl-cache profile to be applied in the storage class. *** This bug has been marked as a duplicate of bug 1693084 ***
