[Pacemaker] Can somebody please explain pengine's urge to move all resources?

[Raoul Bhatia [IPAX]]

hi,

i have a 2node cluster with drbd+nfs+webservices(clones)

basically, i have some rules:

1. promote drbd before starting fs+nfs-server (group_www_data)
> order drbd_before_group_www_data : ms_drbd_www:promote group_www_data:start

2. start nfs-server (group_www_data) before nfsclient+apache
(clone_webservice)
> order group_www_data_before_webservices : group_www_data:start clone_webservice:start

3. start ftp-server after everything is up:
> order fs_www_before_pure-ftpd 0: clone_webservice:start pure-ftpd:start
> order webservices_before_group_ftpd 0: clone_webservice:start group_ftpd:start

(actually, from what i see now, these two rules are redundant, right?)


i also colocate clone_webservice (nfs client) with the ftps server, so
that the ftp server can acutally serve the user's folders ;)
> colocation colo_webservices_group_ftpd inf: group_ftpd clone_webservice:Started


crm status:
>  Resource Group: group_www_data
>      fs_www_data        (ocf::heartbeat:Filesystem):    Started wc01
>      nfs-kernel-server  (lsb:nfs-kernel-server):        Started wc01
>      intip_nfs  (ocf::heartbeat:IPaddr2):       Started wc01
>      backupip_nfs       (ocf::heartbeat:IPaddr2):       Started wc01
...
>  Master/Slave Set: ms_drbd_www
>      Masters: [ wc02 ]
>      Slaves: [ wc01 ]
>  Clone Set: clone_nfs-common
>      Started: [ wc01 wc02 ]
>  Clone Set: clone_webservice
>      Started: [ wc02 wc01 ]
>  Resource Group: group_ftpd
>      intip_ftp  (ocf::heartbeat:IPaddr2):       Started wc01
>      pure-ftpd  (ocf::heartbeat:Pure-FTPd):     Started wc01


now i want to move pure-ftpd from wc01 to wc02:
> crm resource migrate pure-ftpd

imho, as clone_webservice is running on both wc01 and wc02, only
group_ftpd should be stopped and (re-)started.

but pengine thinks:
> Sep 22 11:24:06 wc01 pengine: [4083]: notice: LogActions: Move resource fs_www_data#011(Started wc01 -> wc02)
> Sep 22 11:24:06 wc01 pengine: [4083]: notice: LogActions: Move resource nfs-kernel-server#011(Started wc01 -> wc02)
> Sep 22 11:24:06 wc01 pengine: [4083]: notice: LogActions: Move resource intip_nfs#011(Started wc01 -> wc02)
> Sep 22 11:24:06 wc01 pengine: [4083]: notice: LogActions: Move resource backupip_nfs#011(Started wc01 -> wc02)

can someone please explain the reason for that?
hb report atached.

thanks,
raoul
