> Hi,
>
> We are trying to build a HA setup for our servers using DRBD + Corosync +
> pacemaker stack.
>
> Attached is the configuration file for corosync/pacemaker and drbd.
>
> We are getting errors while testing this setup.
> 1. When we stop corosync on Master machine say server1(lock), it is
> Stonith'ed. In this case slave-server2(sher) is promoted to master.
>    But when server1(lock) reboots res_exportfs_export1 is started on both
> the servers and that resource goes into failed state followed by servers
> going into unclean state.
>    Then server1(lock) reboots and server2(sher) is master but in unclean
> state. After server1(lock) comes up, server2(sher) is stonith'ed and
> server1(lock) is slave(the only online node).
>    When server2(sher) comes up, both the servers are slaves and resource
> group(rg_export) is stopped. Then server2(sher) becomes Master and
> server1(lock) is slave and resource group is started.
>    At this point configuration becomes stable.
>
>
> PFA logs(syslog) of server2(sher) after it is promoted to master till it is
> first rebooted when resource exportfs goes into failed state.
>
> Please let us know if the configuration is appropriate. From the logs we
> could not figure out exact reason of resource failure.
> Your comment on this scenario will be very helpful.
>
> Thanks,
> Priyanka
