And whatabout SBD (a.k.a. poison pill). I've used it reliably with 3 SBDs
on a streched cluster. Neverr failed to kill the node.

Thanks Honza. I guess qnetd+booth will be best in my case as you also
suggested.

Rohit,
I dont think my question was very clear. I am strictly NO for STONITH.
STONITH is limited only for kvm or HP machines. That's the reason I don't
Nope, stonith is not limited only for KVM or HP machine. There is huge
amount of fence agents for various HW and VMs

STONITH is limited only for kvm or HP machines. That's the reason I don't
want to use STONITH.
What my question is can I use booth with nodes of a single cluster also
(similar to qdevice)? So idea is to use booth arbitrator for

Why not? qdevice/booth are handling the split-brain scenario, keeping one
master only even in case of local/geo network disjoints. Can you please
clarify more on this.
Yeah, you are right. I don't
Rohit,
Thanks Honja. That's helpful.
Let's say I don't use qnetd, can I achieve same with booth arbitrator?
That means to have two two-node clusters. Two-node cluster without
fencing is strictly no.
Booth arbitrator works for geo-clusters, can the same arbitrator be reused
for local

Booth arbitrator works for geo-clusters, can the same arbitrator be reused
for local clusters as well?
Is it even possible technically?

Rohit,
Hi Team,
Can I execute corosync-qnetd and booth-arbitrator on the same VM in a
different geo site? What's the recommendation? Will it have any limitations
in a production deployment?
There is no technical limitation. Both qnetd and booth are very
lightweight and work just fine with
