Getting OVM ISCSI Multipathing right with a clustered 7320
Hi folks,
Im setting up an OVM 3.2.1 cluster pool using block storage on a 7320 and I cant get the multipathing working as expected to survive a cluster failover.... so I likely got it wrong :-)
The objective is to have 2 storage fabrics completely isolated and dedicated to forward iSCSI traffic.
The configuration is the following:
- The storage pool is own by the first head.
- Each OVM server is configured with 2 NICS in distinct layer2/3 domains (mimicking 2 independent fabrics)
- First ZFS head has interface igb2 in network A with an iSCSI target configured on that interface
- Second ZFS head has interface igb3 in network B with an iSCSI target configured on that interface
