Idea/Dev test: HowTo use GlusterFS as SR on XCP-ng
Or someone who quickly builds a package for gluster
@olivierlambert I moved it to the Concepts area of the wiki and added a clarification. Should be clear now.
(I just found my own warning in this thread https://xcp-ng.org/forum/topic/291/how-to-use-glusterfs-driver-with-xcp-ng-7-5/10)
So whats needed to build an official XCP-ng Gluster package? Or is someone in the process of buiding one?
The more I read about GlusterFS the more it attracts to me as a good stable solution I want to use.
The priority is to mastering SMAPIv3 first. Because this will be the foundation of all future storage integrations.
This is not a trivial task, but this is the main mission of @ronan-a
@olivierlambert ok, so I hold back
SMAPIv3 is full or surprises… Some of them are great (no need to modify statically some XAPI config files to add a new SR backend!!) but some aren't (perfs issues)

We got an
ext4-ngdriver already working. But benchmarks are… not good so far. So now the goal is to investigate to find the bottleneck. Oddly enough, even while using what we thing the same datapath than SMAPIv1 (yes you can do that), it's still slower.
In the end, we must really understand exactly how this whole stuff works, so we could improve it ourselves (there is no public
masterbranch for some repo, thanks Citrix…)
edit: we are using the datapath coded by Citrix, so they should suffer the same problem than us for GFS2. I don't understand how this could be "production ready", but that's another story.

@olivierlambert just checking in, the wiki still says its not production ready...
@borzel how is your implementation performing over last few months...
Depends on what you expect about production ready. Eg this driver is used since 2y in XOSAN without issues. But we support XOSAN ourselves, not the driver alone.
