Hi dear list members !
I have a procluster project I'm working on right now and I have a little
problem I'd like you to help me with.
I'm configuring Pacemaker and Corosync.
But when pacemaker starts DRBD, it detects a split brain and the status is:
drbd driver loaded OK; device status:
version: 8.3.13 (api:88/proto:86-96)
srcversion: C0F510A918B92928FB51EE3
m:res cs ro ds p mounted
fstype
0:r0 StandAlone Primary/Unknown UpToDate/DUnknown r-----
On both servers.
But If I start it using the standard init script, it's all fine.
Here are my configs:
DRBD:
---------------------------------------------------------------------------------
resource r0 {
syncer {
rate 1000M;
}
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
become-primary-on both;
}
net {
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
cram-hmac-alg sha1;
shared-secret "secret";
}
on web1dev {
device /dev/drbd0;
disk /dev/mapper/groupe1-data;
address 192.168.77.212:7789;
meta-disk internal;
}
on web2dev {
device /dev/drbd0;
disk /dev/mapper/groupe1-data;
address 192.168.77.213:7789;
meta-disk internal;
}
}
---------------------------------------------------------------------------------
And Pacemaker:
---------------------------------------------------------------------------------
primitive p_drbd ocf:linbit:drbd \
params drbd_resource="r0" \
op start interval="0" timeout="240s" \
op promote interval="0" timeout="90s" \
op demote interval="0" timeout="90s" \
op notify interval="0" timeout="90s" \
op stop interval="0" timeout="100s" \
op monitor interval="20s" role="Slave" timeout="20s" \
op monitor interval="10s" role="Master" timeout="20s"
ms ms_drbd p_drbd \
meta master-max="2" clone-max="2" notify="true" is-managed="true"
---------------------------------------------------------------------------------
What could be possibly wrong ?
