Right, "do not depend" should be "depend" there. Thanks for catching it :)

The problem reported is that there is no space between "inf:" and "(" -
the parser in crmsh doesn't handle missing spaces between tokens right
now.

Cheers,

No, colocating sets works indeed differently, syntax is correct (for XML
examples in pacemaker explained that is ...)

You need to create set consisting of single resource. I do not know if
it possible to colocate set and single resource - none of examples show it.

[ClusterLabs] crm shell 2.1.2 manual bug?

[Ulrich Windl]

Hi!

For crmsh-2.1.2+git132.gbc9fde0-18.2 I think there's a bug in the manual 
describing resource sets:

   sequential
   If true, the resources in the set do not depend on each other 
internally. Setting sequential to true implies a strict order of dependency 
within the set.

Obviously "true" cannot mean both: "do not depend" and "depend". My guess is 
that the first true has to be false.

In addition, isn't the syntax with resource sets missing something (despite 
from the description)?:

colocation  : resource_sets
 [node-attribute=]

comparing to

colocation  : [:] [:]
 [node-attribute=]

I expected the with-rsc to be at the end also when using resource sets...

I came across this when trying to add a colocation like this:
colocation col_LV inf:( cln_LV cln_LV-L1 cln_LV-L2 cln_ML cln_ML-L1 cln_ML-L2 ) 
cln_VMs

crm complained about this:
ERROR: 1: syntax in role: Unmatched opening bracket near  parsing 
'colocation ...'
ERROR: 2: syntax: Unknown command near  parsing 'cln_ml-l2 ) cln_VMs'
(note the lower case)

Regards,
Ulrich
