There is a saying in link
https://gluster.readthedocs.org/en/latest/Troubleshooting/split-brain/ as below.
This is done by observing the afr changelog extended attributes of the file on
the bricks using the getfattr command; then identifying the type of split-brain
(data split-brain, metadata split-brain, entry split-brain or split-brain due
to gfid-mismatch); and finally determining which of the bricks contains the
'good copy' of the file.
So the gfid-mismatch is also a split-brain.
But I found that "gluster volume heal gv0 info split-brain" can't show
split-brain entry due to gfid-mismatch.
My question is following:
1.Which command can be used to show split-brain due to gfid-mismatch?
2.How to heal it？Is it same as data split-brain？
Thanks，
Xin
