Hi All,
I'm running two machines with SLES9 SP1( 2.6.5-7.139-default ). I
have setup with drbd (drbd-0.7.5-0.3) and heartbeat (heartbeat-1.2.3-2.3) to
form a HA cluster. Both the machines are of same configuration. Here comes the
drbd.conf file
( I )
resource r01 {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt -
f";
startup {
wfc-timeout 0;
degr-wfc-timeout 120; # 2 minutes.
}
disk {
on-io-error detach;
}
net {
timeout 60; # 6 seconds (unit = 0.1 seconds)
connect-int 10; # 10 seconds (unit = 1 second)
ping-int 10; # 10 seconds (unit = 1 second)
max-buffers 32;
max-epoch-size 2048;
ko-count 4;
on-disconnect reconnect;
}
syncer {
rate 10M;
group 1;
al-extents 257;
}
on host1 {
device /dev/drbd0;
disk /dev/sde;
address 10.0.0.10:7788;
meta-disk internal;
}
on host2{
device /dev/drbd0;
disk /dev/sdc;
address 10.0.0.30:7788;
meta-disk internal;
}
}
( II ) DRBD status

( III )
After the device creation, I tried to create a filesystem on a particular drbd
device. But after sometime the kernel panics.
Can anyone of you please tell me whether there is any problems in the setup or
DRBD works only for local hard disk(IDE) and not for scsi device. Is my
understanding is right??
Thanks in advance..
Cordially
