Re: [ovirt-users] Ovirt and Gluster

Could you point me to this message? Of particular note, the RHSS version of Gluster uses afr-v1, whereas the community version uses afr-v2. Exactly how the mismatch will manifest itself or what problems may result has not been described. Which version of RHEV are you using? RHEVM 3.5 should be compatible with glusterfs 3.6. It is recommended to use 3 way replication for the gluster volume that you use as storage domain.

But for anyone that cares, we've been running oVirt 3.5 and GlusterFS 3.6 for about three months in production now. We run a Gluster cluster and a seperate virtualization hosts cluster. The Gluster cluster is installed, configured and managed seperately from oVirt as there is no way to have a seperate storage network in oVirt 3.5 I run something comparable but using a split dns to get a separate storage network but also a storage cluster and virt cluster. The storage is managed through ovirt though because of the split-dns. There have been no specific incompatibility issues, so we are very happy. But as we don't use every feature mileage may vary. Question: do you use fuse mounts or libgfapi? I use libgfapi in test, using special vdsm packages and need to test if rebooting gluster nodes has an impact on running VMs. Select GlusterFS storage domain in oVirt isn't guaranteed to give you libgfapi! Joop It's production, so I'm using regular FUSE mounts. Although slower, it works at least with supported packages. We did spend some extra on hardware and are conservatively staying close to the Red Hat Storage hardware requirements. So that means RAID10 for now and a seperate SSD stroge volume. For our enterprise customers we are waiting for oVirt 3.6 and will spend even more on hardware (RDMA, Datacenter bridging, PCIe SSD's, etc) but we have to do a lot more testing before rolling it out.
