SO the question is : what about ovirtmgmt network for gluster
replication when gluster domain is provided by ovirt nodes?
I suppose it could be a problem too, couldn't it?
yes that is correct, using ovirtmgmt for non management traffic is not a
good idea.
In case I have a dedicated network for gluster for the nodes, how can
i configure it?
Generally there two ways to go about this:
1. add a new network role 'gluster replication' and then adjust the
engine code to pass the network with this role as parameter to the
replication verb in VDSM.
2. in the replication verb in the UI let the user choose which network
to use for the replication.
I am not familiar with the replication verb so I might be missing
something but otherwise I think that solution 2 is more simple and less
invasive then requiring a new network role.
Bala, is there a means to select, for each node, which IP address is to
be used for replication? AFAICT we use the host fqdn, which most
probably resolves to the ovirtmgmt device.
what is "replication verb in the UI"? Inside UI when I click "create
volume" and then "add Bricks" buttons I can only select "Server" that
in my case is a drop down menu containing only ip addresses of my 2
hypervisors....
Or simply do you mean development steps to integrate this missing
functionality in oVirt with steps 1. and 2.?
I am probably missing some background around Gluster, could you share
what triggers the gluster replication?
[Adding Amar from gluster team]
There's no user interface way to trigger replication.
Gianluca, I assume you do not mean geo-replication but replication of
files when volume is of replicated type.
Currently, we do not have a way to specify the network to be used when
gluster communicates with peers.
Like Joop mentioned in a separate mail, if you use FQDN to add host to
the engine, and FQDN resolves differently for internal and external
communication, gluster would then use the internal network for its
communication
