<pre wrap="">I dont think rrp is well tested by upstream.
You might want to ask on the corosync ML to be sure.

<pre wrap="">Hi,
I have two network cards and configured corosync-1.2.7 with
rrp_mode: active
at first corosync-cfg -s tells me
Printing ring status.
Local node ID 1210452490
RING ID 0
id = 10.10.38.72
status = ring 0 active with no faults
RING ID 1
id = 10.10.40.115
status = ring 1 active with no faults
after a very short time I see the following:
RING ID 1
id = 10.10.40.115
status = Incrementing problem counter for seqid 1352 iface
10.10.40.115 to [3 of 10]
and finally:
RING ID 1
id = 10.10.40.115
status = Marking seqid 1390 ringid 1 interface 10.10.40.115 FAULTY -
adminisrtative intervention required.
Anybody being successful at all using rrp_mode with corosync?

I use rrp_mode: active with two network bonds (4 network cards) and
what I can tell you is that when I perform tests by shutting down the
switch ports for one of the bonds, it starts to increment the counter
then marks the ring as faulty, just as you mentioned, which is normal
because I just shut the ports.<br>
<br>
If you're encountering this without having network connectivity
problems, then yes, it's an issue, otherwise, when the connection per
ring is lost, that's the normal output.<br>
<br>
Also when the network connectivity is restored the ring doesn't restore
it's previous condition automatically, it's a feature to be implemented
in the corosync 2.y.z branch (a.k.a. Weaver's Needle). For now after
restoring the network connectivity to get the ring back you either do a
corosync-cfgtool -r or have some script monitor and do it for you.<br>
