Hi all,
so I've been playing arround a little bit with setting up a 3 node
cluster, and all seems to work fine when I do the start of the drbd
resources manually. So basically here is my setup, in this current setup
I don't use a virtual ip to connect my stacked resource on. But I don't
really think that's the issue right now. Let me just break it down by
showing you first of all my drbd resource files.
On every node I have 3 ethernet connections for the moment, so ubox1 and
ubox2 are connected via crosslink on the network 10.10.0.0 and
ubox1,ubox2,ubox3 are connected on the network 10.15.0.0
r0.res
---------
resource r0 {
syncer { rate 100M; }
device /dev/drbd0;
disk /dev/sdb1;
meta-disk internal;
on ubox1 {
address 10.10.0.1:8801;
}
on ubox2 {
address 10.10.0.2:8801;
}
}
r0-stacked.res
---------------------
resource r0-stacked {
protocol A;
syncer { rate 100M; }
stacked-on-top-of r0 {
device /dev/drbd10;
address 10.15.0.1:7789;
}
on ubox3 {
device /dev/drbd10;
disk /dev/sdb1;
address 10.15.0.3:7789;
meta-disk internal;
}
}

Once every node is started I get this in crm_mon and /proc/drbd
Online: [ ubox2 ubox3 ubox1 ]
Full list of resources:
Master/Slave Set: ms_drbd_r0
Masters: [ ubox1 ]
Slaves: [ ubox2 ]
Master/Slave Set: ms_drbd_r0S
Masters: [ ubox1 ]
Migration summary:
* Node ubox2:
* Node ubox1:
* Node ubox3:
Now I don't really know why my master/slave resource ms_drbd_r0S doesn't
show me a Slave in crm_mon -rf, well I hope someone can give me a hint
of what I did wrong, it has to be something with the pacemaker rules.
Even the target-role doesn't change to started. Thanks a lot for helping
me out. I am really kind of lost. Thanks
Btw, these are the outputs of the logs that I get on ubox3
