Created 12 node cluster 2. Create tiered volume with Hot tier as (6 x 2) and Cold tier as (2 x (6 + 2) = 16) 3. Fuse Mount the volume on 3 clients RHEL7.2,RHEl7.1 and RHEL6.7 4. Start creating data from each client: Client 1: ========= [root@dj ~]# crefi --multi -n 10 -b 10 -d 10 --max=1024k --min=5k --random -T 5 -t text -I 5 --fop=create /mnt/fuse/ Client 2: ========= [root@mia ~]# cd /mnt/fuse/ [root@mia fuse]# for i in {1..10}; do cp -rf /etc etc.$i ; sleep 100 ; done Client 3: ========= [root@wingo fuse]# for i in {1..999}; do dd if=/dev/zero of=dd.$i bs=1M count=1 ; sleep 10 ; done 5. After a while, the data creation of client 1 and client 2 should be completed while the data creation from client 3 will still be inprogress 6. At this point the data creation will be of only 1 file from client 3 in every 10 sec.

COMMIT: http://review.gluster.org/12440 committed in release-3.7 by Pranith Kumar Karampuri (pkarampu) ------ commit 9a0e3a7ecc61e47a0780708f86efc0170b8a85db Author: Ashish Pandey <aspandey> Date: Fri Oct 23 13:27:51 2015 +0530 cluster/ec: update version and size on good bricks Problem: readdir/readdirp fops calls [f]xattrop with fop->good which contain only one brick for these operations. That causes xattrop to be failed as it requires at least "minimum" number of brick. Solution: Use lock->good_mask to call xattrop. lock->good_mask contain all the good locked bricks on which the previous write opearion was successfull.
