Hello, manual for 1.0 (and 1.1) reports this for Advisory Ordering: On the other-hand, when score="0" is specified for a constraint, the constraint is considered optional and only has an effect when both resources are stopping and or starting. Any change in state by the first resource will have no effect on the then resource.
(there is also a link to a http://www.clusterlabs.org/mediawiki/images/d/d6/Ordering_Explained.pdf to go deeper with constraints, but it seems broken right now...) Is this also true for order defined between a group and a clone and not between resources? Because I have this config order apache_after_nfsd 0: nfs-group apache_clone where group nfs-group lv_drbd0 ClusterIP NfsFS nfssrv \ meta target-role="Started" group apache_group nfsclient apache \ meta target-role="Started" clone apache_clone apache_group \ meta target-role="Started" And when I have both nodes up but with corosync stoppped on both and I start corosync on one node, I see in logs that: - inside nfs-group the lv_drbd0 (linbit drbd resource) is just promoted but the following components (nfssrv in particular) have not started yet - the nfsclient part of apache_clone tries to start, but fails because the nfssrv is not in place yet I get the same problem if I change into order apache_after_nfsd 0: nfssrv apache_clone So I presume the problem could be caused by the fact that the second part is a clone and not a resource? or a bug? I can eventually send the whole config. Setting a value different from 0 for the interval parameter of op start for nfsclient doesn't make sense, correct? What would it determine? A start every x seconds of the resource? At the end of the process I have: [r...@webtest1 ]# crm_mon -fr1 ============ Last updated: Thu May 20 17:58:38 2010 Stack: openais Current DC: webtest1. - partition WITHOUT quorum Version: 1.0.8-9881a7350d6182bae9e8e557cf20a3cc5dac3ee7 2 Nodes configured, 2 expected votes 4 Resources configured. ============ Online: [ webtest1. ] OFFLINE: [ webtest2. ] Full list of resources: Master/Slave Set: NfsData Masters: [ webtest1. ] Stopped: [ nfsdrbd:1 ] Resource Group: nfs-group lv_nfsdata_drbd (ocf::heartbeat:LVM): Started webtest1.
