[ClusterLabs] pcs problem

[Tomas Jelinek]

Hi Madison,

This issue partially originates in pacemaker. Pacemaker documents 
allowed target-role values to be capitalized, e.g. Stopped, Started, 
etc. So pcs expects the status xml produced by pacemaker to follow this 
and the target-role values to be in this form. Unfortunately, the 
reality doesn't match the documentation - pacemaker keeps the 
target-role value in whatever format entered by the user.

This is not an issue as long as 'pcs resource disable' command is used 
to set target-role, as that sets the value in the expected format. The 
problem happens when target-role is set by other means and the expected 
format is not followed.

The issue is tracked in RHEL-92043 
<https://issues.redhat.com/browse/RHEL-92043>. It has been fixed in pcs 
in 1f4db60 
<https://github.com/ClusterLabs/pcs/commit/1f4db601021a291fe229496dfc3a150a53dcc201> 
for pcs-0.12 branch and 945ecd9 
<https://github.com/ClusterLabs/pcs/commit/945ecd9a863d7a95ac6fc8ef4207c52b953b78a9> 
for pcs-0.11 branch. With this fix, pcs is case-insensitive when reading 
target-role from status xml. The fix will be included in the upcoming 
upstream releases 0.12.1 and 0.11.10

The fix has also been released in RHEL packages pcs-0.12.0-3.el10_0.2 
and pcs-0.11.9-2.el9_6.1 and upgrading to those should resolve the 
issue. However, upon checking Alma Linux pcs packages, it looks like 
Alma Linux decided not to include the fix in their pcs-0.11.9-2.el9_6.1 
package.

As a workaround, set the target-role meta attribute of resources in CIB 
to one of Started, Stopped, Promoted, Unpromoted.

Regards,
Tomas
