Hi all,
would you mind sending me examples of your crm config for a dual primary
DRBD resource?
I used the one on
http://www.drbd.org/users-guide/s-ocfs2-pacemaker.html
and on
http://www.clusterlabs.org/wiki/Dual_Primary_DRBD_%2B_OCFS2
and they both result into split brain, except for when I start drbd
manually first.
They clearly should not. Rather than soliciting other people's
configurations and then try to adapt yours based on that, why don't you
upload _your_ CIB (not just a "crm configure dump", but a full "cibadmin
-Q") and your DRBD configuration to your pastebin/pastie/fpaste and let
people tell you where your problem is?
OK, I posted the drbd.conf on http://pastebin.com/SQe9YxhY
cibadmin -Q is on http://pastebin.com/gTZqsACq
The split brain logging is on http://pastebin.com/7unKKkdi .
I somehow think you added some "--force" or "--overwrite-data-of-peer"
to some drbdadm/drbdsetup primary invocation?
Could this be some sort of timing issue? Manually things are find,
but there are some seconds in between the primary promotions.
OK, seems to be some sort of timing issue. I "fixed" this by adding a
"sleep 1" in the RA right before the "do_drbdadm primary $DRBD_RESOURCE"
line.
I'm surprised though that I'm the first one to run into this.
