Description RHOS Integration 2014-01-21 14:28:35 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/pnfs.

Description:

The NFS drivers in cinder/brick use NFS 3.0 by default on the client side for NFS communications. NFS4.1 or pNFS seems to be a better alternative considering performance and hence needs to be enabled as default option in brick for NFS related operations. The NFS clients will start by using NFS 4.1 for mouting exports, in case of any failures will fallback to older NFS version. We might need it in nova as well, its a matter of further analysis.

Did not made it into Juno, tracking for Kilo feature freeze

Comment 3 Sean Cohen 2015-03-16 13:56:01 UTC

Did not made it into Kilo, pushing to rhos‑8.0 review,

Comment 4 Jon Schlueter 2015-06-19 18:18:02 UTC

Feature is not integrated upstream moving back from modified and unless a decent amount of work is accomplished to get this accepted or backported cleanly and tested it most likely won't make it into RHOS-7.0 GA milestone.

Comment 5 Jon Schlueter 2015-06-19 18:36:18 UTC

On a bit deeper digging this code was actually merged and the blueprint status is stale.  Confirmed that the patch specifed in the blueprint is actually still in effect in the code base and so updating to modified as part of current build.
