<div dir="ltr">Hi, all!<div><br></div><div>I set up the latest clustering sftware versions from CentOS 6.5 repo (pacemaker 1.1.10 + pcs + drbd 8.4.4) on a two-node cluster.</div><div><div><br></div><div>pcs constraint show</div>
<div>Location Constraints:</div><div>Ordering Constraints:<br></div><div> promote ms_u01 then start u01_fs<br></div><div>Colocation Constraints:<br></div><div> u01_fs with ms_u01 (with-rsc-role:Master)<br></div><div><br>
</div></div><div>Now, when I reboot or shut down 'active' server - filesystem gets promoted on the secondry, and filesystem gets mounted - all as expected. However, when I move resource group with pcs resource move - resources are stopped (correct) and FS unmounted, but DRBD resource stays Primary, after some timeout I get failed action "monitor with role:Master" on the "target" server and eventually resource is kept out of the target server.</div>
<div><br></div><div>I tried to add additional ordering constraint, like this:</div><div><br></div><div><div>pcs constraint show</div><div>Location Constraints:</div><div> Resource: OraGroup</div><div> Enabled on: server2 (role: Started)</div>
<div>Ordering Constraints:<br></div><div> promote ms_u01 then start u01_fs<br></div><div> stop u01_fs then demote ms_u01<br></div><div>Colocation Constraints:<br></div><div> u01_fs with ms_u01 (with-rsc-role:Master)<br>
</div><div><br></div></div><div>This did not change anything...</div><div><br></div><div>Am I missing somethig?</div><div><br></div><div><br></div><div>The previous OS (it was OpenSuSE) and software (pacemaker 1.1.8 + crmsh) worked as expected:</div>
