[Gluster-users] gluster 5.6: Gfid mismatch detected

[Hu Bert]

Hi @ll,

today i updated and rebooted the 3 servers of my replicate 3 setup;
after the 3rd one came up again i noticed this error:

[2019-05-22 06:41:26.781165] E [MSGID: 108008]

A simple 'gluster volume heal workdata' didn't help; 'gluster volume
heal workdata info' says:

There's a mismatch in one directory; I tried to follow these instructions:
https://docs.gluster.org/en/latest/Troubleshooting/resolving-splitbrain/

gluster volume heal workdata split-brain source-brick
gluster1:/gluster/md4/workdata
gfid:fe7fdbe8-9a39-4793-8d38-6dfdd3d5089b
Healing gfid:fe7fdbe8-9a39-4793-8d38-6dfdd3d5089b failed: File not in
split-brain.
Volume heal failed.

Is there any other documentation for gfid mismatch and how to resolve this?


Thx,
Hubert
