[ovirt-users] Re: Managed Block Storage and more

The reason why Ceph appeals me over Gluster because of the following reasons. 1. I have more experience with Ceph than Gluster. That is a good reason to pick CEPH. 2. I heard in Managed Block Storage presentation that it leverages storage software to offload storage related tasks. 3. Adding Gluster storage limits to 3 hosts at a time. Only if you wish the nodes to be both Storage and Compute. Yet, you can add as many as you wish as a compute node (won't be part of Gluster) and later you can add them to the Gluster TSP (this requires 3 nodes at a time). 4. I read that there is a limit of maximum 12 hosts in Gluster setup. No such limitation if I go via Ceph. Actually , it's about Red Hat support for RHHI and not for Gluster + oVirt. As both oVirt and Gluster ,that are used, are upstream projects, support is on best effort from the community. In my initial testing I was able to enable Centos repositories in Node Ng but if I remember correctly, there were some librbd versions present in Node Ng which clashed with the version I was trying to install. Does Ceph hyperconverge still make sense? Yes it is. You got the knowledge to run the CEPH part, yet consider talking with some of the devs on the list - as there were some changes recently in oVirt's support for CEPH.

Ceph integration is still in development/experimental and it should be wise to consider Gluster also. It has a great integration and it's quite easy to work with). There are users reporting using CEPH with their oVirt , but I can't tell how good it is. I doubt that oVirt nodes come with CEPH components , so you most probably will need to use a full-blown distro. In general, using extra software on oVirt nodes is quite hard . With such setup, you will need much more nodes than a Gluster setup due to CEPH's requirements.

These hosts can only have one disk which I plan to partition and use for hyper converged setup. As this is my first oVirt cluster I need help in understanding few bits. 1. Is Hyper converged setup possible with Ceph using cinderlib? 2. Can this hyper converged setup be on oVirt Node Next hosts or only Centos? 3. Can I install cinderlib on oVirt Node Next hosts? 4. Are there any pit falls in such a setup?
