<font size="2" face="Courier 10 Pitch">Hi guys.<br>
<br>
With these:<br>
<br>
-> $ pcs resource status REDIS-6381-clone<br>
* Clone Set: REDIS-6381-clone [REDIS-6381] (promotable):<br>
* Promoted: [ ubusrv2 ]<br>
* Unpromoted: [ ubusrv1 ubusrv3 ]<br>
<br>
-> $ pcs resource status PGSQL-PAF-5433-clone<br>
* Clone Set: PGSQL-PAF-5433-clone [PGSQL-PAF-5433]
(promotable):<br>
* Promoted: [ ubusrv1 ]<br>
* Unpromoted: [ ubusrv2 ubusrv3 ]<br>
<br>
-> $ pcs constraint ref REDIS-6381-clone<br>
Resource: REDIS-6381-clone<br>
colocation-REDIS-6381-clone-PGSQL-PAF-5433-clone-INFINITY<br>
<br>
basically promoted Redis should follow promoted pgSQL but it's
not happening, usually it does.<br>
I presume pcs/cluster does something internally which results in
disobeying/ignoring that _colocation_ constraint for these
resources.<br>
I presume scoring might play a role:<br>
REDIS-6385-clone with PGSQL-PAF-5435-clone (score:1001)
(rsc-role:Master) (with-rsc-role:Master)<br>
but usually, that scoring works, only "now" it does not.<br>
Any comments I appreciate much.<br>
thanks, L.<br>
<br>
I looked at pamaker log - snippet below after REDIS-6381-clone
re-enabled - but cannot see explanation for this.<br>

To clarify & answer this one question - redis resource move
_promoted_ manually just fine, thus it's not Redis itself.<br>
Here are node attrs. Seem that cluster insists _ubusrv2_ is somewhat
special/different (for some resources?):<br>
Node Attributes:<br>
* Node: ubusrv1 (1):<br>
* master-PGSQL-PAF-5433 : 1000 <br>
* master-PGSQL-PAF-5435 : 1000 <br>
* master-REDIS : 1 <br>
* master-REDIS-6380 : 1 <br>
* master-REDIS-6382 : 1 <br>
* master-REDIS-6385 : 2 <br>
* Node: ubusrv2 (2):<br>
* master-PGSQL-PAF-5433 : 990 <br>
* master-PGSQL-PAF-5435 : 1001 <br>
* master-REDIS : 1000 <br>
* master-REDIS-6380 : 1000 <br>
* master-REDIS-6382 : 1000 <br>
* master-REDIS-6385 : 2 <br>
* Node: ubusrv3 (3):<br>
* master-PGSQL-PAF-5433 : 1001 <br>
* master-PGSQL-PAF-5435 : 990 <br>
* master-REDIS : 1 <br>
* master-REDIS-6380 : 1 <br>
* master-REDIS-6382 : 1 <br>
* master-REDIS-6385 : 2 <br>
<br>
Is there a doc/manpage where more about those is explained?<br>
thanks, L.<br>
