Of course it does help, otherwise we wouldn't be able to solve any issues :) The first things to look for are messages from lrmd (the local resource manager). That is where the cluster software meets the reality. All resource problems and output from resource agents are logged by lrmd. In perfect world that should be enough to figure almost all issues. Then there are stonithd messages which tell you if/when a node was fenced. The crmd and pengine messages are probably the most difficult to follow and you'd need a bit of experience for that. crmd is the master of the show and pengine is the program which makes resource placement decisions. Logs of crmd and pengine are normally useful only to the expert(s) :) Thanks, Dejan > Richard Marshall > Senior Technical Specialist > Enterprise Technology Group > Arbella Insurance Group > Hours 6 AM - 2 PM Mon. - Fri. > > [email protected] > 617-328-2921 > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Dejan > Muhamedagic > Sent: Tuesday, August 18, 2009 10:09 AM > To: General Linux-HA mailing list > Subject: Re: [Linux-HA] SUSE 10.1 HA > > Hi, > > On Tue, Aug 18, 2009 at 09:57:02AM -0400, Marshall, Richard wrote: > > Hello: > > > > New to HA and would like to ask what logs, files provide information > > to isolate when, why a resource failed over.
