Dear all, I have some problems with zfs implementation issues: I do not really understand what is a DSL directory (I though is was kind of structure listing all datasets + properties..) and what is the unique "Active Dataset" within a DSL directory? To make it clearer , let's say that I have a pool named mypool with two FSs fs1 & fs2 , each of them with several clones/snapshots, what will be the relatec DSL directory(ies?) and corresponding active datasets?
According http://opensolaris.org/os/community/zfs/docs/ondiskformat0822.pdf , the following path has to be taken to reach a file from uberblock uberblock->MOS->root_dataset->DSL object directory -> DSL (active one as I understand) ->FS->...->file How to get to a non active dataset ? DSL object directory links to DSL through dd_head_dataset_object , i do not see any other possible links in dsl_dir_phys structure? I think that those 2 questions are 2 different faces of the same coin.
