[Gluster-users] Volume heal info not reporting files in split brain and core dumping, after upgrading to 3.7.0

[Alessandro De Salvo]

Hi,
I'm facing a strange issue with split brain reporting.
I have upgraded to 3.7.0, after stopping all gluster processes as described in the twiki, on all servers hosting the volumes. The upgrade and the restart was fine, and the volumes are accessible.
However I had two files in split brain that I did not heal before upgrading, so I tried a full heal with 3.7.0. The heal was launched correctly, but when I now perform an heal info there is no output, while the heal statistics says there are actually 2 files in split brain. In the logs I see something like this:

glustershd.log:
[2015-05-29 08:28:43.008373] I [afr-self-heal-entry.c:558:afr_selfheal_entry_do] 0-adsnet-gluster-01-replicate-0: performing entry selfheal on 7fd1262d-949b-402e-96c2-ae487c8d4e27
[2015-05-29 08:28:43.012690] W [client-rpc-fops.c:241:client3_3_mknod_cbk] 0-adsnet-gluster-01-client-1: remote operation failed: Invalid argument. Path: (null)


So, it seems like the files to be healed are not correctly identified, or at least their path is null.
Also, every time I issue a "gluster volume heal <volname> info" a core dump is generated in the log area.
All servers are using the latest CentOS 7.
Any idea why this might be happening and how to solve it?
Thanks,

   Alessandro
