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.

Help : Heartbeat failover not working (vijay patel) ---------------------------------------------------------------------- Message: 1 Date: Wed, 3 Aug 2011 20:42:05 +0530 From: vijay patel <[email protected]> Subject: [drbd-mc] Help : Heartbeat failover not working To: <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Hi, I have configured DRBD and Heartbeat on two nodes for High Availability of NFS. [root@PdCuLx0501p ~]# rpm -qa | grep drbd drbd82-8.2.6-1.el5.centos kmod-drbd82-8.2.6-2 [root@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@PdCuLx0501p ~]# cat /proc/drbd version: 8.2.6 (api:88/proto:86-88) GIT-hash: 3e69822d3bb4920a8c1bfdf7d647169eba7d2eb4 build by buildsvn@c5-x8664-build, 2008-10-03 11:30:17 0: cs:Connected st:Primary/Secondary ds:UpToDate/UpToDate B r--- ns:1453512252 nr:1076780 dw:1454589032 dr:4588973 al:57316104 bm:686 lo:0 pe:0 ua:0 ap:0 oos:0 [root@PdCuLx0501p ~]# 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@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@PdCuLx0501p ~]# cat /etc/ha.d/ha.cf logfacility local0 keepalive 2 deadtime 30 bcast eth0 node PdCuLx0501p node PdCuLx0502s auto_failback on [root@PdCuLx0501p ~]# cat /etc/ha.d/haresources PdCuLx0501p IPaddr::10.153.80.215/24/eth0 drbddisk::r0 Filesystem::/dev/drbd0::/nfs4exports::ext3 nfslock nfs [root@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?
