Sakshi,
        Ashish worked on this logging patch and I believe they are merged now. So this shouldn't happen.

The following message should have their log levels changed to DEBUG:



In dht_fix_layout_of_directory ():
gf_msg (this->name, GF_LOG_INFO, 0,
                                DHT_MSG_SUBVOL_INFO,
                                "subvolume %d (%s): %u chunks", i,
                                priv->subvolumes[i]->name,
                                priv->du_stats[i].chunks);


This message alone took up about 2GB of a 2.9GB rebalance log file.
Comment 7 Nithya Balachandran 2016-09-01 08:45:42 UTC 
Moving this to POST as the patch has been posted upstream:

master: http://review.gluster.org/15343
Comment 8 Atin Mukherjee 2016-09-17 15:23:10 UTC 
Upstream mainline : http://review.gluster.org/15343
Upstream 3.8 : http://review.gluster.org/15413

And the fix is available in rhgs-3.2.0 as part of rebase to GlusterFS 3.8.4.
Comment 11 Prasad Desala 2016-10-06 07:23:53 UTC 
Verified this bug with glusterfs version: 3.8.4-2.el7rhgs.x86_64. 

After the fix, DHT layout logs those are being generated during mkdir creation are no longer seen with default log level. Layout logs are moved to DEBUG level and user will be able to see those logs only if the log level is set to DEBUG.

Hence, moving this bug to verified.
