Description Rachana Patel 2013-09-06 12:43:36 UTC
Description of problem:
cluster.nufa :- When the local brick reaches the minimum disk free limit, NUFA  is not distributing the files to other bricks in the same volume

Version-Release number of selected component (if applicable):
3.4.0.30rhs-2.el6_4.x86_64

How reproducible:
haven't tried

Steps to Reproduce:
1.had a cluster of 3 RHSS. create distributed volume having two bricks. set cluster.nufa on and change cluster.min-free-disk:
[root@DHT3 nufa]# gluster v info nufa-limit
 
Volume Name: nufa-limit
Type: Distribute
Volume ID: a69f3cde-a6d2-4c0b-9711-255f5fbeb438
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: 10.70.37.195:/rhs/brick2/l1
Brick2: 10.70.37.98:/rhs/brick2/l1
Options Reconfigured:
cluster.min-free-disk: 65%
cluster.nufa: on

2. mount this volume on one of RHSS (server should have one brcik) and start creating data.
[root@DHT1 ~]# mount | grep nufa-limit
10.70.37.98:/nufa-limit on /mnt/nufa-limit type fuse.glusterfs (rw,default_permissions,allow_other,max_read=131072)

3. Once cluster.min-free-disk reaches, verify bricks and logs.

[root@DHT1 ~]# df -h /rhs/brick2/l1
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/RHS_vg2-RHS_lv2
                       50G   24G   27G  47% /rhs/brick2

[root@DHT3 nufa]# df -h /rhs/brick2/l1
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/RHS_vg2-RHS_lv2
                       50G  321M   50G   1% /rhs/brick2

Actual results:
When the local brick reaches the minimum disk free limit, NUFA  is not distributing the files to other bricks in the same volume
- log does not have any warning for the same.

Expected results:
 When the local brick reaches the minimum disk free limit, NUFA should distribute the files to other bricks in the same volume
