<br>
I have the following problem:<br>
<br>
I have a 2 node cluster with a dual primary drbd resource. On top<br>
of it sits an OCFS2 file system. nodes: app1a, app1b<br>
<br>
Now today I had the following scenario (occurred several times now):<br>
- crm node standby app1a<br>
- poweroff app1a for hdd replacement (hw raid controller)<br>
- poweron app1a<br>
- crm node online app1a<br>
<br>
all the other resources come back up as expecte, expect the master<br>
slave set for the dual primary drbd.<br>
<br>
here's the relevant portion of my cluster config:<br>
<br>
node <a href="http://app1a.xlhost.de" target="_blank">app1a.xlhost.de</a> \<br>
attributes standby="off"<br>

order ordDRBD0_FSDRBD0 inf: msDRBD0:promote cloneFSDRBD0<br>
order ordO2CB_FSDRBD0 inf: cloneO2CB cloneFSDRBD0<br>
<br>
if i take down both nodes and fire them up again, everything goes back<br>
to normal and msDRBD0 is promoted to master on both nodes.<br>
<br>
I suspect this has something to do with ordering or colocation constraints<br>
but i'm not sure though. i've been staring at this problem for dozens of<br>
times now and a vast amount of googling did not turn up my specific<br>
problem either.<br>
<br>
anybody have a clue? :) any hint in the right direction as where too look<br>
etc. would really be appreciated.<br>
<br>
Thanks in advance for your help and best regards,<br>
