I think that the connectivity RA du jour is ocf:pacemaker:ping.
So probably better to try with that one.

The updates happen at the time monitor runs plus the dampen
interval.

No. Both should get updated.

Don't know. Please try the other RA.

[Linux-HA] pingd resource problem

[Nico Faerber]

Salute

I have some troubles setting up a pingd clone resource.
I'm using pacemaker 1.0.8 with corosync 1.2.0 running on a ubuntu 10.04.

after setting up the resource crm/configure/show gives this:

primitive pingd ocf:pacemaker:pingd \
 params host_list="192.168.250.55" multiplier="100" \
 op monitor interval="15s" timeout="20s" \
 op start interval="0s" timeout="90s" \
 op stop interval="0s" timeout="100s"
clone pingdclone pingd \
 meta globally-unique="false"

with crm_mon i see the clone resource is running:

  Clone Set: pingdclone
  Started: [ zs-lb2 zs-lb1 ]

now i do:

#cibadmin -Q | grep pingd | grep value

   
 
 
   
   

ok, that should be  correct now. But it took a long time until both  
nodes had a value of 100.
before that, one node had value="0", the other had value="100".

when i now edit the cib via crm subshell and add a second ip address  
to host_list, verify and commit i get this:

#cibadmin -Q | grep pingd | grep value

   
 
 
   
   

but both nodes should have value="200" because i am able to ping both  
ip addresses from both nodes manually. or am i wrong?

  why is the cib not up to date? Any hints?

thanks Nico
