Doc Text:
The Shared File System service (manila) supports mounting shared file systems backed by a Ceph File System (CephFS) via the NFSv4 protocol. NFS-Ganesha servers operating on Controller nodes are used to export CephFS to tenants with high availability (HA). Tenants are isolated from one another and may only access CephFS through the provided NFS gateway interface. This new feature is fully integrated into director, enabling CephFS back end deployment and configuration for the Shared File System service.

Description Tom Barron 2017-07-10 16:16:48 UTC
Upstream Pike added the NFS ganesha Ceph driver in devstack and as tech preview in TripleO.  This RFE is to make all changes required to support the CephFS NFS back end in RHOSP product.

This will involve addressing at least the following limitations in the tech preview version:

* de-couple placement and scaling of data-plane nfs-ganesha gateways from
  placment and scaling of manila share service

* provide robust HA for nfs-ganesha gateway service since it is in the storage data path

* assure adequate isolation of tenants from one another and from the backend Ceph public network

* integrate fully with OSPd

Note that de-coupling and separate scaling are deferred to a later release but that the other requirements are still targeted.

Comment 5 Tom Barron 2017-12-06 16:26:03 UTC
510547 has merged upstream and we expect the merge of 521358 is imminent.

Comment 6 Tom Barron 2017-12-18 11:21:55 UTC
Both 510547 and 521358 have merged upstream, moving to POST

Comment 11 Tom Barron 2018-04-20 13:13:51 UTC
1568022 has been verified

Comment 12 Tom Barron 2018-05-15 14:24:45 UTC
1575023 was fixed in 2018-05-10.3 puddle so this one should now be verifiable.

Comment 13 Dustin Schoenbrun 2018-05-18 21:31:00 UTC
I was able to use Yogev's deployment to go through my Polarion test cases and all passed. Marking as verified.
