Description Jorge Silva 2013-09-26 14:56:10 UTC

Description of problem:
I have in increasing number of bad links in the my .glusterfs/xx/xx/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx-> ../../xx/xx/xxxxxxyy-xxyy-xxyy-xxyy-xxxxxxxxxxyy

Version-Release number of selected component (if applicable):
Os: Centos 6.4
Kernel: 2.6.32-358.6.2.el6.x86_64
Type: Replicate
Number of Bricks: 1 x 2 = 2
Bricks : mdadm raid5, lvm, xfs

How reproducible:
Stop Gluster (kill all the glustergd and glusterd), remove .glusterfs directories on both server. Start one of the gluster servers, the .glusterfs directory gets rebuilt.after a day run:

 find /gluster/homes -type l -a ! \( -xtype b -o -xtype c -o -xtype d -o -xtype p -o -xtype f -o -xtype s -o -xtype l \) > ~/bad_files_1

 ~/bad_files_1 is empty

no warnings in the logs files.

wipe out data on second server and remove .glusterfs directory. start gluster on brick 2, run 
gluster volume heal homes

Leave overnight, all data synced. Run on both servers.

find /gluster/homes -type l -a ! \( -xtype b -o -xtype c -o -xtype d -o -xtype p -o -xtype f -o -xtype s -o -xtype l \) > ~/bad_files_1

On both see :

find: `/gluster/homes/.glusterfs/xx/xx/88afd36a-5ffc-4220-8867-506c9c88e1f6': To                                                              o many levels of symbolic links

the files on both server have the identical number of bad entries.

repeat a find a couple of days later and number of bad symbolic links increase.

GlusterFS 3.7.0 has been released (http://www.gluster.org/pipermail/gluster-users/2015-May/021901.html), and the Gluster project maintains N-2 supported releases. The last two releases before 3.7 are still maintained, at the moment these are 3.6 and 3.5.

This bug has been filed against the 3,4 release, and will not get fixed in a 3.4 version any more. Please verify if newer versions are affected with the reported problem. If that is the case, update the bug with a note, and update the version if you can. In case updating the version is not possible, leave a comment in this bug report with the version you tested, and set the "Need additional information the selected bugs from" below the comment box to "bugs".

If there is no response by the end of the month, this bug will get automatically closed.

GlusterFS 3.4.x has reached end-of-life.
