Hi,
I have the following setup:
- order drbd0:promote drbd1:promote
- order drbd1:promote drbd2:promote
- order drbd2:promote all:start
- collocation all drbd2:Master
- all is a group of resources, drbd{0..3} are drbd ms resources.
I want to migrate the resources based on ping connectivity to a
default gateway. Based on
http://www.clusterlabs.org/wiki/Pingd_with_resources_on_different_networks
and http://www.clusterlabs.org/wiki/Example_configurations I've
tried the following:
- primitive ping ocf:pacemaker:ping params host_list=1.2.3.4
multiplier=100 op monitor interval=5s timeout=5s
- clone ping_clone ping meta globally-unique=false
- location ping_nok all \
rule $id="ping_nok-rule" -inf: not_defined ping_clone or
ping_clone number:lte 0
Use pingd to reference the attribute in the location constraint.
Not to be disrespectful, but after 3 days being stuck on this issue,
I don't exactly understand how to do that. Could you please provide
an example.
Thank you in advance.
The example you reference lists:
primitive pingdnet1 ocf:pacemaker:pingd \
params host_list=192.168.23.1 \
name=pingdnet1
^^^^^^^^^^^^^^
clone cl-pingdnet1 pingdnet1
^^^^^^^^^
param name default is pingd,
and is the attribute name to be used in the location constraints.
You will need to reference pingd in you location constraint, or set an
explicit name in the primitive definition, and reference that.
Your ping primitive sets the default 'pingd' attribute,
but you reference some 'ping_clone' attribute,
which apparently no-one really references.
I've finally managed to finish the setup with the indications received
above, the behavior is the expected one. Also, I've tried the
ocf:pacemaker:pingd and even though it does the reachability tests
properly, it fails to update the cib upon restoring the connectivity, I
had to manually run attrd_updater -R to get the resources to start
again, therefore I'm going with ocf:pacemaker:ping.
Anyways, Dejan, Lars, Andrew, thank you all very much for your help.
Best regards,
Dan
