Dynamic pools pretty much have to be enabled to associate a pset with a zone, don't they? So if I set pset.min=1, pset.max=2, it will run with 1 CPU because I don't have a resource optimization objective? Just trying to make sure I understand this. thanks.

Each pset will have at least the minimum number of CPUs, but may have more. No pset, other than the default pset, can have more CPUs than pset.max. The number of CPUs allocated to a set will not change unless someone intervenes manually (e.g. by transferring a CPU between sets) or a resource optimisation objective is set and dynamic pools are enabled. If you want more details about libpool's allocation strategy take a look at: http://cvs.opensolaris.org/source/xref/on/usr/src/lib/libpool/common/poo l_commit.c In particular the comment at line 902 for the pset_allocate_imp() function should be enlightening.

If i set up pools for each zone with associated processor sets, each with a pset.min and pset.max, but don't set a dynamic pool objective, is there a default objective? or do the zones run with the minimum specified number of cpu's and never change? > Thanks > > > This message posted from opensolaris.org > _______________________________________________ > zones-discuss mailing list > zones-discuss@opensolaris.org -- Gary Pennington Solaris Kernel Development, Sun Microsystems [EMAIL PROTECTED] _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
