Hi all,
I just recently started testing out oVirt in our lab. I’m using CentOS 7 on my
hosts and using the hosted-engine model, and the oVirt 3.6 repository. I have
NFS storage. I ran across what I think is a bug of some sort, and I’m curious
if anyone else has tried this or know what’s going on.
I wanted to be able to expose the NFS server (not necessarily the share used
for oVirt storage domains, but other shares on the NFS server) to VMs running
on my host (currently my setup only involves a single host). I have two
10GbaseT interfaced bonded together on the hose with two VLAN networks on it
currently, one for the management network, one for storage. When the
hosted-engine deployment was set up, I ended up with an ovirtmgmt interface
that was bridged to my infrastructure vlan interface (vlan 1080). So, I added
another network in my oVirt cluster named VM-Storage with vlan 1092 (my storage
network). Here is approximately how I expected this to end up:
bond0 - (bonded interface)
- bond0.1092 (STORAGE - vlan interface)
- VM-storage (bridged interface)
- bond0.1080 (INFR - van interface)
- ovirtmgmt (bridged interface)
However, when I did network setup on the host, and dragged the VM-Storage
network over to the network interface and hit OK, the UI just froze, and for a
few seconds I checked on the host via ssh session and the VM-storage bridge was
setup, then the server just rebooted. After it rebooted, my vlan interface was
no longer there and it seems like both the hosted engine VM and the host ended
up being rebooted. In thinking about it, I may have caused at least a
temporary outage with my NFS storage when the new bridged interface was set up
which caused (maybe) the HA agent to think the hosted engine vm went away or
something, and that cause the reboots. Not entirely sure, but this was
certainly unexpected. I have tried several times and the same result each time.
I did check that any other VM network with a different VLAN ID provisions just
fine on the host, so I assume there’s something that happens when this storage
network is provisioned that is catching oVirt off-guard somehow.
Anyone else have this issue before? Can I solve this by adding another host,
then moving the hosted-engine to a different host while I add the storage
network to each host?
Thanks.
