[Linux-cluster] clusvcadm Relocate <group> causing reboot.

[jayesh.shinde]

Hi All ,

I have query about the "clusvcadm" and "post_join_delay"
I am using the high traffic Mail Server  with  "2 node active-active 
DRBD  + RHCS."  ( i.e node1 and node2)

 From node1 server when I try to relocate the group to other server , 
the node1 get  fence and get reboot and all services get shift to node2
For relocating the service I am using following command  :--

clusvcadm -r imap2 -m node2

I am not able to figure out why the node1 get fence and reboot while 
relocating.  Some time the group relocation from one node to other 
happen smoothly. I have notice that without cluster when I run 
"/etc/init.d/cyrus-imapd stop" it takes long time. ( say 3 min). Its 
Because  cyrus-imapd do the import export inside the local db files.

in the cluster.conf I have below line
<fence_daemon post_fail_delay="0" post_join_delay="3"/>

If I change the post_join_delay="180" then will this help to solve  my 
problem ?

Is there any way to avoid rebooting while relocating group to another 
node , please suggest.

Regards
Jayesh Shinde
