Description of problem: Execute fileop test and in the nfs.log we get lot of input/output errors Version-Release number of selected component (if applicable): glusterfs-3.7.5-5.el7rhgs.x86_64 How reproducible: always Steps to Reproduce: 1. create a volume of 6x2 type 2. mount the volume over vers=3 3. execute fileop test Actual results: the fileop test finishes, but the nfs.log reports loads of input/output error, [2015-11-16 16:57:09.974247] E [MSGID: 108008] [afr-transaction.c:1981:afr_transaction] 0-vol0-replicate-0: Failing SETATTR on gfid 93fce9eb-10f2-4d6e-b524-4a5d5ad4a005: split-brain observed.

Looks more like an AFR issue to me, changing components.
Hi Saurabh, Are the files actually in split-brain? Could you check the afr xattrs (getfattr -d -m . -e hex /brick(s)/file) and the output of `gluster vol heal volname info` and 'gluster v heal volname info split-brain`?
I tried to reproduce the problem and as you can see that there are no files listed for split-brain [root@nfs12 ~]# gluster volume heal vol0 info Brick 10.70.46.8:/rhs/brick1/d1r1 Number of entries: 0 Brick 10.70.46.25:/rhs/brick1/d1r2 Number of entries: 0 Brick 10.70.46.27:/rhs/brick1/d2r1 Number of entries: 0 Brick 10.70.46.39:/rhs/brick1/d2r2 Number of entries: 0 [root@nfs12 ~]# [root@nfs12 ~]# [root@nfs12 ~]# gluster volume heal vol0 info split-brain Brick 10.70.46.8:/rhs/brick1/d1r1 Number of entries in split-brain: 0 Brick 10.70.46.25:/rhs/brick1/d1r2 Number of entries in split-brain: 0 Brick 10.70.46.27:/rhs/brick1/d2r1 Number of entries in split-brain: 0 Brick 10.70.46.39:/rhs/brick1/d2r2 Number of entries in split-brain: 0
