[Pacemaker] crm_attribte failed with Multiple attributes match

[Andrew Beekhof]

I ran your script, all I get is:

[root at pcmk-4 ~]# ./test.sh 0
scope=status  name=master-vmrd-res:0 value=(null)
Error performing operation: The object/attribute does not exist
scope=status  name=master-vmrd-res:0 value=1
scope=status  name=master-vmrd-res:0 value=2
scope=status  name=master-vmrd-res:0 value=3
scope=status  name=master-vmrd-res:0 value=4
scope=status  name=master-vmrd-res:0 value=5
scope=status  name=master-vmrd-res:0 value=6
scope=status  name=master-vmrd-res:0 value=7

which is pretty much what I'd expect.
Perhaps try a more recent version?
