Hi,
Actually, my gluster volume is distribute-replicate so I should provide the attributes on all the bricks. Here they are: 1. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-0=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-1=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAACqqqqq/////w==
2. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-0=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-1=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAACqqqqq/////w==
3. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-2=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-3=0sAAAAAAAAAAEAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAAAAAAAAVVVVVA==
4. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-2=0sAAAAAAAAAAEAAAAA trusted.afr.md1-client-3=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAAAAAAAAVVVVVA==
5. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-4=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-5=0sAAAAAAAAAAEAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAABVVVVVqqqqqQ==
6. # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-4=0sAAAAAAAAAAEAAAAA trusted.afr.md1-client-5=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAABVVVVVqqqqqQ==
so it seems in fact that there are discrepancies between 3-4 and 5-6 (replicate pairs).

"gluster volume heal md1 info split-brain" returns approximatively 2000 files (already divided by 2 due to replicate volume). So manually repairing each split-brain is unfeasable. Before scripting some procedure, I need to be sure that I will not harm further the gluster system.
Moreover, I noticed that the messages printed in the logs are all about directories, e.g. [2015-03-12 10:06:53.423856] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-md1-replicate-1: Unable to self-heal contents of '/root' (possible split-brain). Please delete the file from all but the preferred subvolume.- Pending matrix: [ [ 0 1 ] [ 1 0 ] ] [2015-03-12 10:06:53.424005] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-md1-replicate-2: Unable to self-heal contents of '/root' (possible split-brain).

Getting the attributes of that directory on each brick gives me for the first # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-0=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-1=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAACqqqqq/////w==
and for the second # file: data/glusterfs/md1/brick1/root trusted.afr.md1-client-0=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-1=0sAAAAAAAAAAAAAAAA trusted.gfid=0s3DmMvSq0QOyf7T1ZN2VPSw== trusted.glusterfs.dht=0sAAAAAQAAAACqqqqq/////w==
so it seems that there are both rigorously identical. However, according to your split -brain tutorial, none of them has 0x000000000000000000000000. What 0sAAAAAAAAAAAAAAAA means in fact ?
Should I change both attributes on each directory to 0x000000000000000000000000 ?
Many thanks,
A.

If not, could you go through that once and try the steps given there? Do let us know if something is not clear in the doc. -Krutika From: "Alessandro Ipe" <Alessandro.Ipe@xxxxxxxx> Well, it is even worse. Now when doing a "ls -R" on the volume results in a lot of [2015-03-11 11:18:31.957505] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-md1-replicate-2: Unable to self-heal contents of '/library' (possible split-brain).
