Description Rachana Patel 2013-08-21 05:45:22 EDT
Description of problem:
cluster.nufa :- if RHSS has more than one brick/sub-vol and nufa is on , than any files created from that RHSS mount points are stored only on brick/sub-vol

Version-Release number of selected component (if applicable):
3.4.0.20rhs-2.el6rhs.x86_64

How reproducible:
always

Steps to Reproduce:
1.create DHT volume having more than one brick on one RHSS node and turn on cluster.nufa; mount that volum eon same RHSS node

[root@DVM1 ~]# gluster v info nufa
 
Volume Name: nufa
Type: Distribute
Volume ID: ec850869-99e9-497c-b650-b5c1443acb3d
Status: Started
Number of Bricks: 3
Transport-type: tcp
Bricks:
Brick1: 10.70.37.128:/rhs/brick3/n1
Brick2: 10.70.37.128:/rhs/brick3/n2
Brick3: 10.70.37.192:/rhs/brick3/n1
Options Reconfigured:
cluster.nufa: on
[root@DVM1 ~]# mkdir /mnt/nufa
[root@DVM1 ~]# mount -t glusterfs 10.70.37.192:/nufa /mnt/nufa


2. create files from mount point
[root@DVM1 ~]# cd /mnt/nufa
[root@DVM1 nufa]# touch f{1..20}


3. check on all bricks that where files are actually stored
[root@DVM1 nufa]# ls -l /rhs/brick3/n1
