[Jake Smith]

Vijay - you will have better luck posting these questions in the DRBD users mailing list as this (mc) list is specifically for the java management console.

Hi, 

I have configured DRBD and Heartbeat on two nodes for High Availability of NFS. 

[root at PdCuLx0501p ~]# rpm -qa | grep drbd 
drbd82-8.2.6-1.el5.centos 
kmod-drbd82-8.2.6-2 


[root at PdCuLx0501p ~]# rpm -qa | grep heartbeat 
heartbeat-pils-2.1.4-11.el5 
heartbeat-ldirectord-2.1.4-11.el5 
heartbeat-stonith-2.1.4-11.el5 
heartbeat-devel-2.1.4-11.el5 
heartbeat-2.1.4-11.el5 
heartbeat-gui-2.1.4-11.el5 


[root at PdCuLx0501p ~]# cat /proc/drbd 
version: 8.2.6 (api:88/proto:86-88)

drbd status is connected and in sync. Now when i stop heartbeat service on primary server to test failover my primary server gets rebooted. I can see secondary server acquiring virtual ip and mounting the common share but on client i am getting error "permission denied. /mnt/nfs is readonly". 

Here is my configuration files: 

[root at PdCuLx0501p ~]# cat /etc/drbd.conf 
global { 
usage-count ask; 
} 

common { 
syncer { rate 250M; } 
} 
resource r0 { 
protocol B; 
#incon-degr-cmd "halt -f"; 
startup { 
degr-wfc-timeout 120; # 2 minutes. 
} 
disk { 
on-io-error detach; 
} 
net { 
} 
syncer { 
rate 250M; 
#group 1; 
al-extents 257; 
} 
on PdCuLx0501p { 
device /dev/drbd0; 
meta-disk /dev/sdb2[0]; 
disk /dev/sdb3; 
address 10.153.80.213:7788; 
} 
on PdCuLx0502s { 
device /dev/drbd0; 
meta-disk /dev/sdb2[0]; 
disk /dev/sdb3; 
address 10.153.80.214:7788; 
} 
} 


[root at PdCuLx0501p ~]# cat /etc/ha.d/ha.cf 
logfacility local0 
keepalive 2 
deadtime 30 
bcast eth0 
node PdCuLx0501p 
node PdCuLx0502s 
auto_failback on 


[root at PdCuLx0501p ~]# cat /etc/ha.d/haresources 
PdCuLx0501p IPaddr::10.153.80.215/24/eth0 drbddisk::r0 Filesystem::/dev/drbd0::/nfs4exports::ext3 nfslock nfs 


[root at PdCuLx0501p ~]# cat /etc/ha.d/authkeys 
auth 3 
3 md5 50f4a0bd87aedb051e93b6aa16f1433e 


Now what is the problem in my configuration? Why i am not able to mount files system from client when seconday has acquired primary status and why primary gets restarted on stopping heartbeat service? 

Regards, 
Vijay
