<div>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. <br>

What does the mount log on the hypervisor say? Could you attach
that? <br>

<div>As a workaround I've executed "<span class="s1"><b>yum</b></span><span
class="s2"> 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? </span></div>
