Description spandura 2013-11-14 06:51:19 EST
Description of problem:
If a file is in split-brain state and the file has hardlinks, then the hardlinks are not reported in the output of "volume heal <volume_name> info split-brain" command execution. 

This information is necessary for resolving the split-brain on the bricks. All the hardlinks are to be deleted on the bricks in order to completely resolve the files from split-brain state. 

Version-Release number of selected component (if applicable):
glusterfs built on Oct 21 2013 14:00:58

How reproducible:

Steps to Reproduce:
1. Create a 1 x 3 replicate volume. Set "nfs.disable" to "on". Set "self-heal-daemon" to "off". Start the volume. 

2. Create 3 fuse mount points. Create a file "file1" from mount point. Create 2 hardlinks to the file. 

3. Bring down brick1 and brick2. 

4. From mount1 edit file "file1"

5. Bring down brick3. Bring back brick2. 

6. From mount2 edit file "file1"

7. Bring down brick2. bring back brick1. 

8. From mount3 edit file "file1"

9. set "self-heal-daemon" volume option to "on" 

10. Bring back brick2 and brick3. { Now the file is in data-split-brain state }

11. Execute: "gluster volume heal <volume_name> info split-brain" 

Actual results:
root@rhs-client11 [Nov-14-2013-11:49:25] >gluster v heal vol_rep info split-brain
Gathering list of split brain entries on volume vol_rep has been successful

Expected results:
Hardlinks also to be reported under split-brain command output.
