Globally-unique clone cleanup on remote nodes

Nov 18, 2014, 9:27 PM

Post #1 of 6 (1473 views)

Hi all,

just an observation.

I have a globally-unique clone with 50 instances in a cluster consisting
of one cluster node and 3 remote bare-metal nodes.
When I run "crm_resource -C -r '<g_u_clone>'" (crmsh does that for me),
it writes that it expects to receive 50 answers (although it writes 4
lines for per-instance requests, one for each node).

Is that correct (I would expect to see 200 there)?

Version is c191bf3.

Best,
Vladislav

At most it would be 151, not 200.

How many times do you see this printed?

printf("Cleaning up %s on %s\n", rsc->id, host_uname);

200. Ok, I didn't count, but this is printed once per instance per node,
50 instances, 4 nodes (one cluster node and 3 remote ones).

ah, 201 then.

But actually, we don't expect replies from pacemaker-remote nodes.

Aha, got the idea, so what I see is correct, right?

Btw, if I run the same command per remote node, no expectation line is
printed at all.

Thanks.
