Now on 1st server (cluster1), the Filesystem resource cannot start. the gfs2 filesystem can't be mounted.<br><br>this is the crm configuration<br clear="all">[root@cluster2 ~]# crm configure show<br>node cluster1 \<br>

<br>but when i check the mount, there is no mount from drbd<br><br>there is another strange thing, the 1st server (cluster1) cannot reboot. it hangs with message 'please standby while rebooting the system'. in the reboot process, there are 2 failed action which is related to fencing. i didn't configure any fencing yet. one of the failed action is : <br>
'stopping cluster<br>leaving fence domain .... found dlm lockspace /sys/kernel/dlm/web<br>fence_tool : cannot leave due to active system [FAILED]'<br><br>please help me with this problem<br><br>-- <br>Best Regards,<br>
