I reproduced my cluster problem again and got this error from /var/log/message So, I think the reason is fencing wrongly configured. And I may have to focus on Configure Fencing Device. Here is my log: Jun 17 22:32:36 server2 fenced[6559]: fenced 3.0.12.1 started Jun 17 22:32:36 server2 dlm_controld[6573]: dlm_controld 3.0.12.1 started Jun 17 22:32:37 server2 gfs_controld[6634]: gfs_controld 3.0.12.1 started Jun 17 22:33:29 server2 fenced[6559]: fencing node server1 Jun 17 22:33:29 server2 fenced[6559]: fence server1 dev 0.0 agent none result: error config agent Jun 17 22:33:29 server2 fenced[6559]: fence server1 failed Jun 17 22:33:32 server2 fenced[6559]: fencing node server1 Jun 17 22:33:32 server2 fenced[6559]: fence server1 dev 0.0 agent none result: error config agent Jun 17 22:33:32 server2 fenced[6559]: fence server1 failed Jun 17 22:33:35 server2 fenced[6559]: fencing node server1 Jun 17 22:33:35 server2 fenced[6559]: fence server1 dev 0.0 agent none result: error config agent Jun 17 22:33:35 server2 fenced[6559]: fence server1 failed -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Bob Peterson Sent: Tuesday, June 17, 2014 7:09 PM To: linux clustering Subject: Re: Two-node cluster GFS2 confusing ----- Original Message ----- > Hi, here is my dmesg after failed: > > GFS2: fsid=: Trying to join cluster "lock_dlm", "mycluster:web" > dlm: Using TCP for communications > GFS2: fsid=mycluster:web.0: Joined cluster.
