In a similar vein, the documentation for 'sacctmgr' says
Note: the QOS that can be used at a given account in the hierarchy are
inherited by the children of that account.
However, if I do the following:
$ sacctmgr modify account name=root set qos+=medium,short
the result is
Modified account associations...
C = soroban A = root
C = soroban A = anemometry U = alice
C = soroban A = anemometry U = bob
C = soroban A = barometry U = carol
C = soroban A = barometry U = dave
C = soroban A = calorimetry U = ethel
...
To me this looks as if the QOS are in fact being explicitly added to
each association. In this case, will a new association added within
this hierarchy automatically be associated with the QOS available to the
other associations?
Cheers,
Loris
