We got to know gluster only in the 3.1 version, and what I see from the internet, all other versions were somewhat harder to manage. Thus: great job, this (3.1) is how it should be and is. > We still enable a significant amount of tuning, we have just changed the way they are applied, please see - http://www.gluster.com/community/documentation/index.php/Gluster_3.1:_Setting_Volume_Options. I know this page. Most of the options are pretty obvious and self-explaining, some are not. cluster.stripe-block-size ( list such as : "*.jpg:1,abc*:2" ) - I don't really get this (Block size == number of bricks?). diagnostics.latency-measurement ( yes/no ) diagnostics.dump-fd-stats ( yes/no ) - what are these good for? Some explanation for all of these options would really help. It seems to me that in previous version one could modify volume files and create own subvolumes (different translators and such). Nowadays it seems that this is no longer possible. The documentation on the different translators seems to be all for <=3.0 What would I do if I wanted to change the number of io threads in [...] volume cloud-io-threads type performance/io-threads option thread-count 16 subvolumes cloud-locks end-volume [...] What happened to all these translators? http://www.gluster.com/community/documentation/index.php/Translators Are they no longer there in 3.1? Can they be configured somehow? Anyway, I do not miss them, but from the list above it seems that some translators might be handy for some cases.
