Steps to Reproduce:
1.Create a 6 node master cluster and a 6-node slave cluster
2.Create a 9x2 DR master volume and slave volume
3.Create and start non-root geo-replication session
4. Mount the master and slave volume
5. Create data  on the master mount :

for i in {create,chmod,chown,chgrp,hardlink,symlink,truncate,rename}; do echo "------------------- This iteration is for fop $i -----------------" >> /root/result ; crefi --multi -n 5 -b 10 -d 10 --max=10k --min=5k --random -T 10 -t text --fop=$i /mnt/master/ 1>/dev/null 2>&1 ; sleep 10 ; echo "---Arequal Master for $i---" >> /root/result ; /root/arequal-checksum -p /mnt/master/ >> /root/result ; sleep 600 ;  echo "---Arequal Slave for $i---" >> /root/result ; /root/arequal-checksum -p /mnt/slave/ >> /root/result ; done

All fops are synced (create,chmod,chgrp,chown,hardlink,symlink,truncate,rename) 
How reproducible:
Have seen this twice on non-root setup out of 4 trials.

    geo-rep: Filter out volume-mark xattr
    The volume-mark xattr, maintained at brick root
    of slave volume is specific to geo-replication
    and should be filtered out for all other clients.
    It should also be filtered out from list getxattr
    from all mounts including geo-rep mount as it
    might cause rsync to read and set.
