RHEL: I don't expect that the packages will ever be part of the RHEL Samba build. The ones for Gluster aren't, as precident. But I don't speak for Red Hat. :) I also don't work on RHEL. I work on Fedora. So all of this is written from the point of view of Fedora 23. I'm working on straightening out my Fedora 24 development setup. As far as state of the world? CTDB: It can be made to work, but I don't recommend it at this time. The settings needed aren't friendly to CephFS, and I would not recommend this in production today. ACLs: Aren't implemented in vfs_ceph, because I still have to submit the refactored vfs_ceph code to the Samba team list, but I ran into testing issues on the CephFS side, regarding ACL setting, if the Gluster side works, I may just see if we can push these anyways. The refactoring unifies the ACL handling between vfs_ceph and vfs_gluster. Working absent those two issues: Seems ok, for modern Ceph bits. most recent Jewel should be "ok", as I understand it. I did my work on pre-release Jewel bits. I recommend looking at my presentation that I gave at SambaXP. http://sambaxp.org/ day 3. It may be out of date in a few spots, but it should be close.
