Re: [Linux-cluster] clurgmgrd : <notice> relocating a service to better node



Still shy on info. I shall assume that you are trying to start 'my_proc'
on 'my_blade2.my_domain' and it moves to 'my_blade1.my_domain'? What do
the syslogs say when you start the resource? What is the output of
'cman_tool status'.

Please, provide all data you think might be relevant. It's easier to
ignore useless data than it is to guess about important but missing data.

A few additional comments:

* When sharing configs, please leave everything as is, except passwords.
Trying to obfuscate specific-but-harmless issues, you may remove the problem

* clean_start="1" is not wise. It's telling the node to assume that the
peer is dead when it starts but can't talk to it's peer. This is asking
for a split-brain.

* missing_as_off="1" is also dangerous, as it makes an assumption about
a node's state, rather than verifying it.

* You have three IP resources defined, but only one in use.
