Hi Friends,
I am having DRBD and Heartbeat setup for Production file server. I am having
two servers in cluster with following versions on RHEL 5.8.
[vpatel@Pd02 ~]$ rpm -qa | grep drbd
drbd82-8.2.6-1.el5.centos
kmod-drbd82-8.2.6-2
[vpatel@Pd02 ~]$ rpm -qa | grep heartbeat
heartbeat-gui-2.1.4-11.el5
heartbeat-pils-2.1.4-11.el5
heartbeat-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
Till now every thing was working fine. Today we had some outage and one of the
drbd server was shutdown abruptly. Once server came up both servers became out
of sync. On secondary server i found message of split brain detected in logs.
In order to sync two servers when i am running 'connect' command, sync is
getting started but gets stalled after few seconds. Below is the output of the
commands i tried.
DRBD Secondary Server :
[root@Pd02 ~]# drbdadm disconnect all
[root@Pd02 ~]# drbdadm -- --discard-my-data connect all
[root@Pd02 ~]# cat /proc/drbd

stalled
I tried to force sync via invalidate command but got following message.
[root@Pd02 ~]# drbdadm invalidate all
Device '/dev/drbd0' is configured!
Command 'drbdmeta /dev/drbd0 v08 /dev/sdb2 0 invalidate' terminated with exit
code 20
command exited with code 20
Can anyone tell me how can i sync my drbd servers?
Regards,
Vijay _______________________________________________
