[Pacemaker] the instance id of clone is changed after removing constraints

[Junko IKEDA]

Hi,

I have the following resources,

============
Last updated: Mon Mar 29 16:09:53 2010
Stack: openais
Current DC: cspm01 - partition with quorum
Version: 1.0.8-d353c41113af stable-1.0 tip
4 Nodes configured, 4 expected votes
2 Resources configured.
============

Online: [ cspm01 cspm02 cspm03 cspm04 ]

  Resource Group: group01
      gDummy01   (ocf::pacemaker:Dummy): Started cspm01
      gDummy02   (ocf::pacemaker:Dummy): Started cspm01
      gDummy03   (ocf::pacemaker:Dummy): Started cspm01
  Clone Set: clone01
      Started: [ cspm01 cspm04 ]

Operations:
* Node cspm02:
* Node cspm03:
* Node cspm04:
    cDummy01:1: migration-threshold=1
     + (6) start: rc=0 (ok)
     + (7) monitor: interval=10000ms rc=0 (ok)
* Node cspm01:
    gDummy01: migration-threshold=1
     + (8) start: rc=0 (ok)
     + (9) monitor: interval=10000ms rc=0 (ok)
    gDummy02: migration-threshold=1
     + (10) start: rc=0 (ok)
     + (11) monitor: interval=10000ms rc=0 (ok)
    gDummy03: migration-threshold=1
     + (12) start: rc=0 (ok)
     + (13) monitor: interval=10000ms rc=0 (ok)
    cDummy01:0: migration-threshold=1
     + (6) start: rc=0 (ok)
     + (7) monitor: interval=10000ms rc=0 (ok)


call "crm_resource" to move group01 from cspm01 to cspm04.

# crm_resource -M -r group01 -H cspm04 -f -Q

the above operation went well,
but after trying to remove constraints depended on a move command,

# crm_resource -U -r group01

cDummy01:0 on cspm01 switched to cDummy01:1
and
cDummy01:1 on cspm04 switched to cDummy01:0

globally_unique="false".
Why the instance id of clone is changed?


Thanks,
