Hi HIDEO - Thanks for your help. It turned out that I kind of misunderstood OCF requirements and in fact there is no real need to use pgrep and I can fall back to "kill -0" schema to check if a process is up. I'll be busy with some other stuff for a couple of days then I'll provide little bit different patch that shouldn't have all those pgrep problems. Thanks again. -- Serge Dubrouski. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
