Re: [Linux-cluster] Not restarting "max_restart" times before relocating failed service



Digimer,

Out put of rpm -q cman

cman-2.0.115-34.el5

There is no http mentioned in fencedevice, I think email client is inserting it.


Thanks,
Parvez

What does 'rpm -q cman' return?

This looks very odd;
<fencedevice agent="fence_bladecenter"

Please remove this for now;

 <fence_daemon clean_start="1" post_fail_delay="0"
> post_join_delay="0"/>

In general, you don't want to assume a clean start. It's asking for
trouble. The default delays are also sane. You can always come back to
this later after this issue is resolved, if you wish.
