Hi Mark, I need a bit more time for replying. I just wanted to add a few observations and correct some mistakes in my earlier communication. - There are actually 5 different settings, NULL (=unset), none, passive, aggressive and force. These can be set on OSDs and pools. In addition, the blob-size arguments for compression are also available on pools. This gets really confusing and it is not fully documented which settings will take precedence. - In Octopus it seems that the interaction of combinations of OSD- and pool settings has been fixed (at least the case where one of these is NULL). This was a mess in mimic. Its still not clear from the documentation what takes precedence in all possible situations of conflicts. My personal take is that pool-setings are sufficient, the OSD settings could be removed and the mode options could be reduced to none and force, where NULL=none (none is default). As promised, I will return to this in another thread about the small files/tail object handling that will also consider compression.
