iSCSI Failover

[Slijfer]

Goodmorning,

With our setup here, we are trying to build the following configuration:

Primary node -> Secondary node

Master target 0 -> Replicated Master target 0 (slave target)
Master target 1 -> Replicated Master target 1 (slave target)
Replicated Master target 2 (slave target) -> Master target 2
Replicated Master target 3 (slave target) -> Master target 3


So we have 2 targets on the primary node, these targets will be replicated on the secondary target. In case the primary node fails, the data on the targets will become available from the secondary target.

On the other hand, if the secondary node fails, we want to have the data on the targets available from the primary node.

Is this possible? Or can iSCSI Failover only be used for primary to secondary and not back?

Greetings!

hi,

when your primary is back and running from the secondary start sync volumes and after it finishes press the failback button. there is only manual failback possible.

Melik,

This is not exactly what i ment.

We have got 2 servers set up here, both running open-e with 1 iSCSI target, replication enabled. iSCSI Failover is also set-up, it works great, even with a virtual machine running at the moment the primary node fails.

But we wanted to have a 2 way iSCSI Failover, with on both servers 1 target and 1 replication target. At the moment node 1 fails, node 2 will take over the target from node 2. On the other side if node 2 fails, node 1 will take over the target from node 2.

Is it possible to set this up, or is it only possible to have 1 server set up as a primary and 1 as a secondary node?

Greetings!

Currently it is not possibly.

I have made an image which hopefully will explain it a bit better.

This is how our customer wants to have it!
