Hi, I'm looking for a way to show just location constraints, if they exist, for a
cluster. I'm looking for the same data shown in the output of `pcs config` under the
"Location Constraints:" header, but without all the rest, so that I can write a
script that checks if there are any set.
The situation is that sometimes people will perform a failover with `pcs resource move
--master <resource>`, but then forget to follow it up with `pcs resource clear
<resource>`, and then it causes unnecessary failbacks later. As we never want to
have any particular node in the cluster preferred for this resource, I'd like to write a
script that can automatically check for any location constraints being set and either alert
or clear it automatically.
Thank you for any advice!
crm configure show type:location
to see all location constraints
pcs constraint location
to see all location constraints
pcs constraint location show
allows you to filter by resources or nodes
crm configure show type:location and cli-*
to see constraints that are create by crm_resource --move or --ban.
There is no alternative to this in pcs. You can add --full to the pcs
commands above to make them show constraint ids and then look for ids
starting with cli-.
Regards,
Tomas
But you can also simply run "crm_resource --clear" periodically, this
will remove all move/ban constraints on all resources.
