Thanks for your reply ! I have many data folders such as data1,data2... and this data folders contains some files. The data will be disable if one files missed. I use distributed volume storage the data folders and the files of data folder is distributed to all bricks. The all data folders will be disable if one brick down. Fully understand your situation. it's your application characteristic which one file missing will bring the upper layer application not work.So you want to make the impact of brick failure as small as possible. I think out the distributed replica volume,but disk utilization is less than 50% whth replica volume.I can put up with some data missing ,but I cann't tolerate all data being disable. So,I want the data folder storage just one brick,so that ,if one brick down , it has some data folder disable in this brick and other data is well. The capacity cost seems the tradeoff of high availability,if you can't bear it.Two suggestions: 1. replace replica with EC to overcome the low disk usage while maybe bring some performance issue.However I'm new to glusterfs and not very sure about the EC implementation detail and the stableness. 2. let your application layer to do some work solve the disperse of the data without glusterfs involving it.
