Created attachment 991297 [details] rebalance log file Description of problem: ====================== Created a 2x(8+3) distribute disperse volume and tried to reduce that to 1x(4+2) plain disperse volume by removing bricks. Given gluster volume remove-brick command and after some time the server has crashed. Version-Release number of selected component (if applicable): ============================================================= glusterfs 3.7dev built on Feb 8 2015 01:04:29 How reproducible: ================= Tried only once Steps to Reproduce: 1. Create a 2x(8+3) distribute-disperse volume 2. Create huge number of files and directories with multiple block sizes 3. Convert it to plain disperse of 1x(4+2) volume.
