Thank you Sahina, Yes, I setup my gluster volume outside oVirt, and as you guessed my volumes are identified by name, not by IP: [RDKVM1][root@rdkvm1 ~]# gluster volume info gluvol2 Volume Name: gluvol2 Type: Replicate Volume ID: 3c1e9936-4cce-4a21-83f3-ac8611348484 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: rdkvm1-data:/data/sdc1/gluvol2 Brick2: rdkvm2-data:/data/sdc1/gluvol2 Options Reconfigured: nfs.disable: on performance.readdir-ahead: on transport.address-family: inet
From the engine host:
[RDHEAD1][root@rdhead1 ~]# nslookup rdkvm1-data Server: 10.3.231.123 Address: 10.3.231.123#53 Name: rdkvm1-data.rd-connect.eu Address: 10.3.10.5 [RDHEAD1][root@rdhead1 ~]# nslookup rdkvm2-data Server: 10.3.231.123 Address: 10.3.231.123#53 Name: rdkvm2-data.rd-connect.eu Address: 10.3.10.6 [RDHEAD1][root@rdhead1 ~]# host rdkvm1-data rdkvm1-data.rd-connect.eu has address 10.3.10.5 Note that the engine does not have a connection to 10.3.10.x despite it resolves names. I have the system in production. Is there a secure way to test the patch in this circumstance?

Hi!
Looks like you have setup your gluster volume outside of oVirt and your bricks are identified via "rdkvm1-data" , "rdkvm2-data" and not the IP addresses associated with the gluster network ( 10.3.10.5, 10.3.10.6) What does "gluster volume info gluvol2" return?
Currently we cannot identify multiple FQDNs for a host and resolve it correctly to the correct network. There was a patch - https://gerrit.ovirt.org/#/c/60083/, can you review if it will solve your usecase? Will rdkvm1-data be resolvable from engine?

Hello,
I have latest version of ovirt 4 installed on a Centos 7, 2 hypervisor nodes (rdkvm[1-2]) and 1 ovirt-engine node (rdhead1).
I receive the following warning in the logs despite of having the gluster network set up. Everything is running fine.

My ovirt-engine node is not connected to the gluster network directly. The glusterNetwork is defined in the cluster and is attached to bond0 interface of rdkvm1 and rdkvm2.

I tried to manually attach the network_id to the volume bricks, but after a while it gets emptied:
[RDHEAD1][root@rdhead1 squid-in-a-can]# su - postgres -c "psql -d engine -c \"update gluster_volume_bricks set network_id='628ed584-feaf-4952-908c-5b2d654c0731' \"" UPDATE 4
Look:

How can I solve this situation?
