Hi, I realised that gluster 3.7.8 was released for GA. So I updated manually using "yum -y install glusterfs*" gluster get's updated normally, but unfortunately things stopped to work completely. ovirt_hosted_engine_ha was not able to connect to my gluster storage domain (as you can see below). I'm not using ovirt + gluster in hyperconverged way. I have 3 external gluster hosts.

As a workaround I've executed "yum downgrade glusterfs*" and after doing this ovirt started to work again...but as a collateral effect now I can't migrate my vm's anymore. On the vdsm logs I can see the following errors when trying to manually migrate a any VM.... Anyone knows how to fix it?
