Version-Release number of selected component (if applicable): [root@apandey glusterfs]# glusterfs --version glusterfs 3.8dev built on Dec 21 2015 10:49:16 Repository revision: git://git.gluster.com/glusterfs.git Copyright (c) 2006-2013 Red Hat, Inc. <http://www.redhat.com/> GlusterFS comes with ABSOLUTELY NO WARRANTY. How reproducible: 100% Steps to Reproduce: 1. Create a tier volume with 2 X (4+2) disperse volume and 6 X (2) replica volume. 2. Mount it through fuse. 3. start writing various files with multiple threads on mount point. crefi --multi -n 10 -b 10 -d 10 --max=1024k --min=5k --random -T 5 -t text -I 5 --fop=create /mnt/gfs Actual results: After some time (1 min to 30 min) CRASH happens in disperse volume.
