It's completely free and easy to use XOSAN deployement process is complex, rely on various bricks and linked to xen-orchesra.com, so that would have require a lot of effort to make it available directly from the sources in a usable way.

But if you want to do it yourself, it's also possible:

create a VM in each host of your pool you want to have in the cluster
install gluster server in each, create the cluster
install gluster client in XS
modify the file SM driver into XenServer to fit with Gluster
restart the toolstack
mount it

This way, you could also bench it

Not a published blog post (still in draft) but here is some bench done, please follow this link and keep it for yourself

We hope to make it for the end of the month (phase II) with a robust health status and flexibility (XOSAN full diagnostic, allow to replace in one click any faulty node, and everything auto heal itself).

Also, we'll try to release the Gluster driver in Open Source for those who want to connect XenServer to an existing Gluster or create their own XOSAN manually.

XOSAN will be an extra product of Xen Orchestra (but you can purchase even in XOA Free), including the turnkey side (and believe me it's not trivial) with full diag status and health + flexibility, including pro support on it obviously.

We'll try to make a Phase III before the official release, with tiering capabilities (HDD + SSD cache to get best of both world).

We started to create the official doc here: https://xen-orchestra.com/docs/xosan.html

Remember the goals of XOSAN:

protect your data thanks to replication of data on multiple (from 2 to 16) hosts
provide XenServer high availability without buying a NAS or a SAN
give you flexibility to grow your storage by adding new nodes
work on all kind of hardware, from HDDs to SSDs
fully monitored solution

@olivier Very Impressed! Nice work

@olivier Very nice numbers there, and I'm excited you're looking to release XOSAN to the community!

olivier

@dustinb3403 It won't be XOSAN to the community. XOSAN is like XOA, a turnkey packaged solution.

You'll be able to mount a gluster volume when we'll open the Gluster driver (which allows to create a SR of Gluster type in short). Then you can do whatever you want with that, but you'll need to monitor it yourself, and understand how Gluster works. Something you won't require by using XOSAN

Also a trial version of XOSAN will be available for people who want to test it and bench it quickly (literally in few clicks)

@olivier Two comments, these links don't work

Lastly, if you are converting your native language to English have you considered a translation or proofing service?

Doc is not completed because the product isn't. Consider it as a draft.
Blog post is still a draft

Are you using XOA or XO from Source?

Edit: Assuming you're using the XO from Source - https://github.com/xcp-ng/xcp/wiki/XOSAN

If you have XOA, the Bates team would be the best source of information to help you get this deployed.

@junaidmehmood take a screenshot of your XOA webpage so I can verify some things.
