Description Len DiMaggio 2007-02-07 21:37:48 UTC

Description of problem:
Intermittent/recurring problem - when cluster is deleted, sometimes a node is
not affected

Version-Release number of selected component (if applicable):
luci-0.8-30.el5
ricci-0.8-30.el5

How reproducible:
10% - 25%? Saw it once today

Steps to Reproduce:
1. Create a multi-node cluster and delete it
2. On some nodes, sometimes, cluster.conf is not deleted, cman and rgmanager are
not stopped, or have their boot settings set to off - details are included below

Actual results:
Sometimes a node is not cleaned up

Expected results:
All nodes should be removed from the cluster

Additional info:


->  /etc/cluster/cluster.conf is not deleted

->  these services' boot settings are not set to off:

[root@tng3-4 ~]# chkconfig --list cman
cman            0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@tng3-4 ~]# chkconfig --list rgmanager
rgmanager       0:off   1:off   2:on    3:on    4:on    5:on    6:off

-> This process is left running:
root      4921  4854  0 09:53 ?        00:00:00 /bin/bash
/etc/rc6.d/K03yum-updatesd stop

As is cman - haven't seen rgmanager left running.

Comment 1 Ryan McCabe 2007-03-06 18:57:44 UTC

The failure to stop the node may be a result of either (or both) Bug #222919 or
Bug #230783

Comment 2 RHEL Program Management 2007-03-21 22:08:41 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

Comment 3 Kiersten (Kerri) Anderson 2007-04-23 17:05:53 UTC

Fixing Product Name.  Cluster Suite was merged into Enterprise Linux for version
5.0.

Comment 4 Ryan McCabe 2007-05-21 22:22:12 UTC

Fixed in my current branch. Before deleting a cluster, we first try to stop the
cluster services on each of the nodes. If this fails, bail out before deleting
any nodes. This should prevent the case where some nodes are deleted, but others
are not (e.g., because a service hangs while stopping).
