[Gluster-users] Failed to mount nfs due to split-brain and Input/Output Error

[Anh Vo]

I am trying to mount nfs to gluster volume and got mount.nfs failure.
Looking at nfs.log I am seeing these entries

Heal info does not show the mentioned gfid (
00000000-0000-0000-0000-000000000001 ) being in split-brain.
