> Regards, > Richard Schuh Although most pages of a "dataspaced DIRC" are paged in from SFS' minidisks (and never paged out), the FST list of the access DIRC is alo built in the dataspace, but that is not mapped to SFS minidisks, so they can be paged out to CP's paging areas. So, for a DIRC with few, but huge files the ratio of pages that can be paged out is small, but for a DIRC with lost of small files... CP IND SPACE will tell you a bit about this. And something some readers may forget: a DIRC that is accessed R/W is never placed in a dataspace. So, all dataspaces SFS creates are d'office R/O, no need to mention "they will be R/O".
