[Gluster-users] gluster 3.4.1 for CentOS 6.4 cannot migrate data correctly

[Zhu, Shan]

Hi,

I found this issue but don't have any information about it.

Gluster 3.4.1 for CentOS 6.4 has problem of migrating data when using "remove-brick". It doesn't migrate data correctly. When I have two subdirectories under each brick, running "remove-brick" with "start" migrates one subdirectory content from each of two bricks.

For example, if I have subdirectories "g1" and "g2" under Bricks 1, 2 and 3, running "remove-brick" with "start" for Brick3 will migrate data from Brick2's "g1" and Brick3's "g2". I don't find the reason why or how it picks those subdirectories.

Tested on two CentOS 6.4 servers, it worked exactly the same.

Gluster 3.4.2 for CentOS 6.4, or 3.4.1 for RHEL 5 do not have the same problem.

I wonder if upgrading 3.4.1 to 3.4.2 on the CentOS 6.4 system would fix the problem, if it actually comes from the attributes which are created by 3.4.1.

Any clue?
