umm.. here are the config details..
I have configured test1 and test2 under heartbeat. when started, test1 did
not automatically assume the virtual IP, and I had to manually enter one for
it... even so if i turn off test1 to simulate a test1 failure, heartbeat
doesn't take over to force the virtual IP on test2
that said, the problem with replication still exist... I am unable to see
any data being replicated on test2. may be i'm looking at the wrong place :S
kindly guid me there..
the conf files are as below..
on test1 the primary node...
test1:~ # cat /etc/ha.d/ha.cf
logfacility local0
keepalive 2
#deadtime 30 # USE THIS!!!
deadtime 10
bcast eth0
node test1 test2

}
disk {

}
net {

syncer {

}
on test1 {

disk /dev/md0;

meta-disk internal;
}
on test2 {
device /dev/drbd0;
disk /dev/md0;
address 192.168.2.62:7788;
meta-disk internal;
}
}
=-=-=-=-=-=-=-=-
all config files are replicated on test2, the secondary node..
test1:~ # cat /proc/drbd

=--=-=-=-=-
Just to clear, I have not performed any mount operation on any of the drbd
nodes.
I'm using seperate interfaces for drbd sync, and heartbeat/client acces...
192.168.1.6x are being used for client access and heartbeat while
192.168.2.6x are used by drbd dedciated sync link.
any help/suggestion greatly appreicated.
