Hi all,
I'm trying to set up HA with DRBD and Heartbeat on two identical RedHat
VM's hosted on Windows VirtualBox. The details about the server(s) drbd
biuld and config are given below:
[root@cpvmdc1 ~]# uname -a

All is fine except the following error/problem that I get when starting the
drbd service:
On the want be "primary":
[root@cpvmdc1 ~]# service drbd start
Starting DRBD resources: [
create res: r0
prepare disk: r0
adjust disk: r0
adjust net: r0:failed(connect:10)
]
.
[root@cpvmdc1 ~]# service drbd status
drbd driver loaded OK; device status:

2011-12-21 17:13:05
m:res cs ro ds p mounted
fstype
0:r0 StandAlone Secondary/Unknown UpToDate/DUnknown r----s
On the "secondary":
[root@cpvmdc2 ~]# service drbd start
Starting DRBD resources: [
create res: r0
prepare disk: r0
adjust disk: r0
adjust net: r0:failed(connect:10)

[root@cpvmdc2 ~]# service drbd status

fstype

For some reason they fail to connect. I have no firewall between/on the
servers and they can ping each other. Trying to connect manually gives me
the following error:
[root@cpvmdc1 ~]# drbdsetup connect r0 ipv4:192.168.1.100:7788 ipv4:
192.168.1.101:7788
r0: Failure: (126) UnknownMandatoryTag
additional info from kernel:
Any idea what this "UnknownMandatoryTag" means?
Thanks in advance for any help or advise.
Igor
