Try to enter it interactively: The crm shell gets what bash (or dash) passes. The quotes are gobbled by bash in that process. Basically, what you type is not what crm sees. I understand the mechanics. It is machine-centric and confusing to some users. It is not absolutely impossible to accept quoted parameters from command line. Quotes are stripped, but these parameters are preserved in single arguments. Right. I really don't understand why's everybody trying to configure the cluster directly from bash instead of doing it in crm configure. CRM shell offers this opportunity, that's why many users try to use it. But, unfortunately, the feature is not uniform with interactive shell. -- Pavel Levshin ___ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
Re: [Pacemaker] How to send email-notification on failure of resource in cluster frame work

Is there any other approach for sending email notification. Last time I checked, crm_mon is not well suited for this purpose. crm_mon has the following option -T, --mail-to=value Send Mail alerts to this user.See also --mail-from, --mail-host, --mail-prefix But you will end-up with obscene amount of e-mails, I was blocked from gmail when I tried to use it once :) For one resource failure you will get 4 e-mails: monitor,stop,start,monitor. Now imagine if it was a most significant member of a group or worse, node failure... nagios would be better suited for this purpose, but, unfortunately, crm_mon is broken (http://developerbugs.linux-foundation.org/show_bug.cgi?id=2344) for quite awhile. I am yet to find a good monitoring solution for pacemaker, hopefully somebody had more success and will share.
