hi~ ,thanks i found it works well after i copy the script to all machines first,is there need to have all script in all machine? if some machine only run tomcat ,some only run squid ,some only run httpd , one tomcat server should has squid script and httpd script after all. even i try to score it in location not to run httpd or squid.
yes? every workers should have all skills even only to one kind of job. 2010/1/20 Andrew Beekhof <and...@beekhof.net> > On Fri, Jan 15, 2010 at 7:23 AM, 梁景明 <futur...@gmail.com> wrote: > > hi ,there are 4 cases in my application to use pacemaker > > case 1: one tomcat unexpected down ,restart it by pacemaker. > > case 2: one tomcat served machine unexpected down ,fail over to another > > machine,back if it recover. > > case 3: some tomcat only run on some special nodes ,the others cant > monitor > > it. > > case 4: one server application runs only after some application started , > it > > means runs by order. > > > > first i try to exam case 1. > > i built a 4 nodes environment to test it ,and standby three nodes .like > this > > > > ============ > > Last updated: Fri Jan 15 11:57:49 2010 > > Stack: openais > > Current DC: bak1 - partition with quorum > > Version: 1.0.5-3840e6b5a305ccb803d29b468556739e75532d56 > > 4 Nodes configured, 4 expected votes > > 1 Resources configured. > > ============ > > > > Node bak1: standby > > Node test1: standby > > Node test2: standby > > Online: [ ubuntu ] > > > > and tomcat lsb script i use the example from the doc on wiki. it started > on > > node ubuntu like this "*sudo sh /etc/init.d/tomcatpace start*" no > problem. > > crm configure : > > > > node bak1 \ > > attributes standby="on" > > node test1 \ > > attributes standby="on" > > node test2 \ > > attributes standby="on" > > node ubuntu > > primitive tomcat lsb:tomcatpace \ > > op monitor interval="10" timeout="30s" \ > > meta migration-threshold="10" target-role="Started" > > > > first i think only ubuntu is online ,so the script only run on ubuntu ,is > it > > right? > > but it fails .it seems to be all the nodes running the script. > > > > Node bak1: standby > > Node test1: standby > > Node test2: standby > > Online: [ ubuntu ] > > > > tomcat (lsb:tomcatpace) Started [ bak1 test1 test2 ] > > > > Failed actions: > > tomcat_monitor_0 (node=bak1, call=2, rc=254, status=complete): > <unknown> > > tomcat_stop_0 (node=bak1, call=3, rc=254, status=complete): <unknown> > > tomcat_monitor_0 (node=test1, call=2, rc=254, status=complete): > > <unknown> > > tomcat_stop_0 (node=test1, call=3, rc=254, status=complete): <unknown> > > tomcat_monitor_0 (node=test2, call=2, rc=254, status=complete): > > <unknown> > > tomcat_stop_0 (node=test2, call=3, rc=254, status=complete): <unknown> > > Have a look at: > http://clusterlabs.org/wiki/FAQ#Resource_is_Too_Active > > In your case, the failed actions indicate the script is not LSB compliant: > > http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/ap-lsb.html > > First thing to do before trying anything else is to fix the script. > > > > > then i added location rule ,but i am not sure about the usage of it ,so > i > > followed the example . > > > > location prefer-ubuntu tomcat \ > > rule $id="prefer-rule" 100: #uname eq ubuntu > > > > is the line to prefer ubuntu node ,and only run on that node ? current > > configure : > > > > node bak1 \ > > attributes standby="on" > > node test1 \ > > attributes standby="on" > > node test2 \ > > attributes standby="on" > > node ubuntu > > primitive tomcat lsb:tomcatpace \ > > op monitor interval="10" timeout="30s" \ > > meta migration-threshold="10" target-role="Started" > > location prefer-ubuntu tomcat \ > > rule $id="prefer-rule" 100: #uname eq ubuntu > > > > but it fails again > > > > Node bak1: standby > > Node test1: standby > > Node test2: standby > > Online: [ ubuntu ] > > > > tomcat (lsb:tomcatpace) Started [ bak1 test1 test2 ] > > > > Failed actions: > > tomcat_monitor_0 (node=bak1, call=2, rc=254, status=complete): > <unknown> > > tomcat_stop_0 (node=bak1, call=3, rc=254, status=complete): <unknown> > > tomcat_monitor_0 (node=test1, call=2, rc=254, status=complete): > <unknown> > > tomcat_stop_0 (node=test1, call=3, rc=254, status=complete): <unknown> > > tomcat_monitor_0 (node=test2, call=2, rc=254, status=complete): > <unknown> ) > > > > thanks for any help . > > _______________________________________________ > > Linux-HA mailing list > > Linux-HA@lists.linux-ha.org > > http://lists.linux-ha.org/mailman/listinfo/linux-ha > > See also: http://linux-ha.org/ReportingProblems > > > _______________________________________________ > Linux-HA mailing list > Linux-HA@lists.linux-ha.org > http://lists.linux-ha.org/mailman/listinfo/linux-ha > See also: http://linux-ha.org/ReportingProblems > _______________________________________________ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
