<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">
<p>There is a Pacemaker bug which cannot be replaced due to legacy tracking and backward compatibility</p>
<p> </p>
<div>colocation FS_WITH_DRBD inf: IP-AND-FS ms_drbd:Master</div>
<div>order DRBD_BEF_FS inf: IP-AND-FS:start ms_drbd:promote </div>
<div> </div>
<div>if colocation and order is specified between 2 Resources then it means the 2nd one is the first and 1st one is the next</div>
<div> </div>
<div>For example,
<div>colocation FS_WITH_DRBD inf: IP-AND-FS ms_drbd:Master</div>
<div>//Actually means first start IP-AND-FS then make ms_drbd as Master</div>
<div>// But in behavior, it is first make ms_drbd as Master and then start IP-AND-FS </div>
<div> </div>
<div>Also for order, it is the same behavior...</div>
<div>
<div>order DRBD_BEF_FS inf: IP-AND-FS:start ms_drbd:promote </div>
<div>
<div>//Actually means first start IP-AND-FS then promote ms_drbd </div>
<div>// But in behavior, it is first promote ms_drbd and then start IP-AND-FS</div>
</div>
</div>
<div> </div>
<div>But when you define order and colocation between 3 or more resources, then the interpretation is fine...</div>
<div> </div>
<div> </div>
<div>Therefore in your scenario, you must configure (as I said)</div>
<div>
<div>colocation FS_WITH_DRBD inf: IP-AND-FS ms_drbd:Master</div>
<div>order DRBD_BEF_FS inf: IP-AND-FS:start ms_drbd:promote </div>
<div> </div>
<div>Though it means opposite, but the behavior is as you expect.(owing to Pacemaker backward compatibility)</div>

<b>Subject:</b> [Pacemaker] [PACEMAKER] Why cant't migrate group resource with collation in drbd resource<br>
</font><br>
</div>
<div></div>
<div>
<div dir="ltr">Hello Everybody,
<div><br>
</div>
<div>I've got a problem (but I am not quite sure if it is not a feature in pacemaker ) that's why I decided to write on that mailing list.</div>
<div><br>
</div>
<div>It comes about migrate resource with collation in drbd resource.</div>
<div><br>
</div>
<div>I've got group including virtual IP and filesystem which is collated with ms resource drbd in mster-slave configuration.</div>
<div><br>
</div>
<div>
<div>============</div>
<div>Last updated: Wed Jan 23 03:40:55 2013</div>
<div>Stack: openais</div>
<div>Current DC: drbd01 - partition with quorum</div>
<div>Version: 1.0.9-74392a28b7f31d7ddc86689598bd23114f58978b</div>
<div>============</div>
<div><br>
</div>
<div>Online: [ drbd01 drbd02 ]</div>
<div><br>
</div>
<div> Master/Slave Set: ms_drbd</div>
<div> Masters: [ drbd01 ]</div>
<div> Slaves: [ drbd02 ]</div>
<div> Resource Group: IP-AND-FS</div>
<div> fs_r1 (ocf::heartbeat:Filesystem): Started drbd01</div>
<div> VIRTUAL-IP (ocf::heartbeat:IPaddr): Started drbd01</div>
</div>
<div><br>
</div>
<div>I would like to migrate that group manually to another node which is slave. So i type in: crm resource migrate IP-AND-FS drbd02</div>
<div><br>
</div>
<div>after that configuration include additional line:</div>
<div><br>
</div>
<div>location cli-prefer-IP-AND-FS IP-AND-FS \</div>
<div> rule $id="cli-prefer-rule-IP-AND-FS" inf: #uname eq drbd02</div>
<div><br>
</div>
<div>and in logs i see:<br>

<div><br>
</div>
<div>but nothing happened resource group is still active on drbd01 node, as well as there was no new master promotion. </div>
<div><br>
</div>
<div>Shouldn't pacemaker automatically promote second node to master and move my resource group ? </div>
<div><br>
</div>
<div><br>
</div>
<div>Below is my test configuration, i will be appreciate for help:</div>
