<br>
1) GlusterFS SSL Cert based access support at subdir
granularity (for glusterfs protocol only)<br>

<br>
<br>
<b>Misc (not fully baked ones, hence haven't open feature
pages</b><b> yet!)</b><b>:</b><br>
<br>
1) GlusterFS proxy server (using containers?)to serve
GlusterFS shares over a private network (for glusterfs
protocol only)<br>
- Disclaimer: Needs more thought and investigation<br>
- This is similar to Netapp's virtual storage server
which is created to serve each share on a pvt network <br>
to achive network level isolation between openstack VMs
and storage array/controller. This makes them to<br>
claim multi-tenancy at network level too.<br>
<br>
2) Enabling non-SSL based access (from a diff. IP) with SSL
based access (from a diff IP) at the same time (for glusterfs
protocol only)<br>
- Openstack Manila Usecase: non-SSL based access can be
used for m-shr service mount and SSL. This is<br>
needed for m-shr housekeeping (update_share_stats being
the primary work) in Manila. SSL based access is<br>
needed for tenants to access GlusterFS shares.<br>
<br>
- Needs more discussion, as this might be security
threat!<br>

glfs_put(object_path, data, metadata)<br>

Subject: [Gluster-devel] What would you like to see in GlusterFS.next?<br>
<br>
Hi All,<br>
<br>
Thanks to everyone who responded to the recent community survey [1], we<br>
have an idea of what you think would be necessary in GlusterFS. I have<br>
tried to collate the wishlist of features under appropriate categories<br>
here [2].<br>
<br>
As a continuation of this, the approaching feature freeze for 3.7 & more<br>
momentum being gained for 4.0 planning, it would be good to understand<br>
what features you would like to see in the next releases of GlusterFS.<br>
To re-state the obvious, 3.x releases will continue to be evolutionary<br>
and 4.0 is planned to be a major release that brings about architectural<br>
improvements for better scale, ease of use and performance. More details<br>
on 4.0 planning can be found at [3].<br>
<br>
Please chip in with your ideas and we will continue to curate the<br>
community feature wishlist with what we learn here.<br>
<br>
Cheers,<br>
Vijay<br>
