Hi,<BR>
<BR>
I have configured DRBD and Heartbeat on two nodes for High Availability of NFS. <BR>
<BR>
[root@PdCuLx0501p ~]# rpm -qa | grep drbd<BR>drbd82-8.2.6-1.el5.centos<BR>kmod-drbd82-8.2.6-2<BR>
<BR>

[root@PdCuLx0501p ~]# cat /proc/drbd<BR>version: 8.2.6 (api:88/proto:86-88)<BR>GIT-hash: 3e69822d3bb4920a8c1bfdf7d647169eba7d2eb4 build by <A href="mailto:buildsvn@c5-x8664-build">buildsvn@c5-x8664-build</A>, 2008-10-03 11:30:17<BR> 0: cs:Connected st:Primary/Secondary ds:UpToDate/UpToDate B r---<BR> ns:1453512252 nr:1076780 dw:1454589032 dr:4588973 al:57316104 bm:686 lo:0 pe:0 ua:0 ap:0 oos:0<BR>[root@PdCuLx0501p ~]#<BR><BR>

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".<BR>
<BR>
Here is my configuration files:<BR>
<BR>
[root@PdCuLx0501p ~]# cat /etc/drbd.conf<BR>global {<BR> usage-count ask;<BR>}<BR>
<BR>common {<BR> syncer { rate 250M; }<BR>}<BR>

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

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

<BR>
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?<BR>
