Hello,
I'm trying to create the following setup in Pacemaker 1.1.10.

op monitor interval="15s" timeout="30s" op start interval="0" timeout="180s" op

pcs resource group add mysql fs_mysql mysqld ip_mysql
pcs constraint colocation add mysql ms_drbd_mysql INFINITY with-rsc-role=Master
pcs constraint order promote ms_drbd_mysql then start mysql
pcs constraint location mysql rule pingd: defined ping
There are two issues here, first, there's a bug in pcs which doesn't recognize
groups in location constraint rules and the second is that the pcs rule syntax
is slightly different than crm.
You should be able to use this command with the latest upstream:
pcs constraint location mysql rule score=pingd defined pingd
Thanks,
Chris
The last line is not working:
[root@linsrv006 ~]# pcs constraint location mysql rule pingd: defined pingd
Error: 'mysql' is not a resource
By the way, can everybody verify the other lines? I'm very now to pcs. Here is
my old configuration.
