postfix recover failed.

I am trying to setup drbd + pacemaker/openais + postfix. Services
started OK, failover..OK.. but when trying to stop postfix service
manually(postfix stop command) of kill postfix service, then postfix
cluster resource failed completely. I though it has to be recovered
from dead status. Pls give me some advices on this.
many thanks,

Hi,

It would, but the stop action failed:

Nov 9 11:07:12 Server1 lrmd: [4682]: info: RA output: (Postfix:stop:stderr) 2009/11/09_11:07:12 ERROR: Postfix returned an error while stopping. 1

This error comes from /usr/sbin/postfix. Not an expert on
postfix, so CC the author of the RA, perhaps he can take a look.

Thanks,

Dejan

looks like it's using a "restart" action, usually coded as "stop" followed
by "start".

If the daemon isn't running to begin with, "stop" will fail.

That sounds like a bug in the RA. If the resource is already stopped, "stop" is meant to return success.

Re: postfix recover failed. [In reply to]

Thanks you all for pointing me out and here is my workaround, it seems
to be working -- just needs a few lines to check the status of postfix
before doing stop command. Are there any better ideas?

The patch looks fine to me. Looks like /usr/sbin/postfix can't
handle this itself. Raoul: Is that actually expected?

Thanks,

Why not: if "postfix stop" fails to stop postfix for whatever reason, it
should return a non-zero value.

Note that "stop" will wait for the daemons to shut down gracefully. Which
means it could potentially block the failover for a while (unlikely worst
case: deadlock).

Seems that 'postfix stop' fails if postfix has already been
stopped. I can't test that, that's why I asked.

Right, though that's not the case here.
