[Gluster-users] Gluster 3.4 on RHCS with OCF resource agents

[Emir Imamagic]

Hello,

Gluster 3.4 provides OCF resource agents which should enable nice 
integration with RHCS. We would like to deploy gluster on two RHCS nodes 
with storage provided via iSCSI. Volume will be distributed and the idea 
is to have RHCS migrate iSCSI LUN & gluster daemon to a single node in 
case of failure of one node. Due to a limited storage we cannot go for 
replicated volume.

We have a similar setup with earlier version of Gluster (3.0) that 
enabled specification of IP address that each gluster daemon should use. 
This enabled usage of virtual IPs and integration with RHCS with service 
resource agent.

Questions are:
1. Is there any documentation on how to use OCF resource agents? I 
checked the source code (glusterd and volume) and the metadata, but 
couldn't figure out how to get two glusterd instances on a same node.

2. Is it possible to have multiple glusterd instances on a same machine 
using virtual IP?

Thanks in advance
