Description Derek Anderson 2004-07-26 16:04:35 UTC

Description of problem:
In a quorate 3-node cluster, attempts to join the fence domain fail:

[root@link-11 root]# cat /proc/cluster/nodes
Node  Votes Exp Sts  Name
   1    1    3   M   link-10
   2    1    3   M   link-11
   3    1    3   M   link-12
[root@link-11 root]# fenced -D
Command Line Arguments:
  name = default
  debug = 1
fenced: fence_domain_add: init_nodes ccs error -1
[root@link-11 root]# ccs_test connect
ccs_connect failed: Connection refused

Raising priority.  This is a blocker for doing anything with a filesystem.

Comment 2 Derek Anderson 2004-07-26 16:40:44 UTC

I can workaround this by running 'ccs_test connect force' on each node
before attempting to join the fence domain.

Comment 3 Jonathan Earl Brassow 2004-07-26 20:48:34 UTC

I was able to reproduce this by:
1. forming a quorate cluster
2. on a single node, do cman_tool leave; cman_tool join

The descriptor held on the cluster manager was becoming invalid.  Now I 
close the descriptor on cman shutdown and attempt to reconnect when it 
becomes available again.

If this is truly the fix for the problem, it may also address bug 128569

Comment 4 Jonathan Earl Brassow 2004-07-26 22:25:12 UTC

Ok, I needed to do an
FD_ZERO(&rset);
before populating the variable.

This appears to be what was causing this bug, as well as 128569

Comment 5 Derek Anderson 2004-07-27 14:34:42 UTC

Works now.

Comment 6 Kiersten (Kerri) Anderson 2004-11-16 19:10:18 UTC

Updating version to the right level in the defects.  Sorry for the storm.
