Description Nick Strugnell 2008-01-25 06:59:07 EST
Description of problem:

Clusvcadm always starts services on the local node, irrespective of options.

We have a 3 node cluster:

and 3 virtual services:

vm:service2 is preferred on node2 according to the failover domain however
running the following on node1:

clusvcadm -e vm:service2
clusvcadm -e vm:service2 -m node2
clusvcadm -e vm:service -F

will _all_ start the service on node1.

The only way to start the service on the correct node is to login to it and run
clusvcadm locally.

We have exactly the same problem using the luci interface.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure a 3 node cluster
2. Configure 3 VM services
3. Configure 3 failover domains so that each VM is preferred on a particular node
4. experiment with either clusvcadm or luci to start up VMs  

Actual results:
VMs will always start up on the local node that clusvcadm is running on, or on
the node that luci is running on

Expected results:
Luci should start up the service on the correct node when 'Start service on node
<blah>' is selected in the menus. clusvcadm should honour the -m and -F flags

Comment 2 Lon Hohberger 2008-01-25 10:07:30 EST
clusvcadm -Fe X          works for me
clusvcadm -r X -[nm] Y   works for me
clusvcadm -e X -[nm] Y   doesn't...?

The -e worked in RHEL50, but regressed in RHEL51:

[root@molly daemons]# clusvcadm -Fe test
Local machine trying to enable service:test...Success
service:test is now running on frederick

Service configuration:
                        <failoverdomain name="all" ordered="1" restricted="1">
                                <failoverdomainnode name="molly" priority="2"/>
                                <failoverdomainnode name="frederick" priority="1"/>
                <service name="test" domain="all"/>

With patch applied, -e -m works too.

Comment 6 Lon Hohberger 2008-01-25 10:16:38 EST
Also tried -e X -F at Nick's suggestion.  I don't understand why that would fail
given the customer's configuration.

First patch makes -e -m work on RHEL5.2
Second patch makes -Fe and -e -m work on RHEL5.1

This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.
Comment 11 Lon Hohberger 2008-01-25 11:08:01 EST
Note that in RHEL 5.2 with central processing enabled, '-F' is implied.  This is
a behavioral change; users wishing the old behavior (e.g. enable X starts X on
node that run clusvcadm) should not use the central processing option.
Comment 12 Lon Hohberger 2008-01-25 11:13:08 EST
