[Ocfs2-users] another fencing question

[Mailing List SVR]

Hi, 

periodically one of on my two nodes cluster is fenced here are the logs:

Jan 14 07:03:50 nvr1-rc kernel: (31,5):o2quo_make_decision:146 ERROR: fencing 
this node because it is connected to a half-quorum of 1 out of 2 nodes which 
doesn't include the lowest active node 0
Jan 14 07:03:50 nvr1-rc kernel: (31,5):o2hb_stop_all_regions:1967 ERROR: 
stopping heartbeat on all active regions.

I'm sure there are no network connectivity problem but it is possible that 
there are heavy IO loads, is this the intended behaviour? Why under heavy load 
the loaded node is fenced?

I'm using ocfs2-1.4.4 on rhel5 kernel-2.6.18-164.6.1.el5

thanks
