Hi,
I came across the exact semantics of the "unique" attribute for
parameters.
Florian's (really great) guide states that
Finally, the unique attribute (allowed values: true or false)
indicates that a specific value must be unique across the
cluster, for this parameter of this particular resource type
Experimenting shows that obviously nothings prevents entering a 'unique'
parameter several times in the same cluster.
In Andrew's "Pacemaker Explained 1.1" Chap 9.5 the 'unique' attribute is
only tied to an optional 'reload' action. It marks this particular
parameter as reloadable.
While cursory browsing through the pacemaker source I could not find any
other usage for this attribute.
Might be the RA guide should state that the name of this attribute is
somewhat misleading and refer to/quote the pacemaker guide.
Regards
Holger
