Re: [Gluster-users] split brain? but where?

[Thing]

Next I ran a test and your find worksI am wondering if I can simply
delete this GFID?

8><-
[root@glusterp2 fb]# find /bricks/brick1/gv0/ -samefile
/bricks/brick1/gv0/.glusterfs/74/75/7475bd15-05a6-45c2-b395-bc9fd3d1763f
/bricks/brick1/gv0/.glusterfs/74/75/7475bd15-05a6-45c2-b395-bc9fd3d1763f
/bricks/brick1/gv0/dell6430-001/virtual-machines-backups/21-3-2018/images/debian9-002.qcow2
[root@glusterp2 fb]#
8><-

On another node also no return,

8><
[root@glusterp1 ~]# find /bricks/brick1/gv0 -samefile
/bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693
/bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693
[root@glusterp1 ~]#
8><

and on the final node,
8><---
[root@glusterp3 ~]# find /bricks/brick1/gv0 -samefile
/bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693
/bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693
[root@glusterp3 ~]#
8><---

So none of the 3 nodes has an actual file?

Re: [Gluster-users] split brain? but where?

[Thing]

I tried looking for a file of the same size and the gfid doesnt show up,

8><---
[root@glusterp2 fb]# pwd

Re: [Gluster-users] split brain? but where?

[Karthik Subrahmanya]

Hi,

Which version of gluster you are using?

You can find which file is that using the following command
find  -samefile //

Please provide the getfatr output of the file which is in split brain.
The steps to recover from split-brain can be found here,
http://gluster.readthedocs.io/en/latest/Troubleshooting/resolving-splitbrain/

HTH,
Karthik
