 Hi,   When trying to access a file on a gluster client (through fuse), I get an 
"Input/output error" message.  Getting the attributes for the file gives me for the first
brick # file: data/glusterfs/md1/brick1/kvm/hail/hail_home.qcow2 trusted.afr.md1-
client-2=0sAAAAAAAAAAAAAAAA trusted.afr.md1-client-3=0sAAABdAAAAAAAAAAA 
trusted.gfid=0sOCFPGCdrQ9uyq2yTTPCKqQ==  while for the second (replicate) 
brick # file: data/glusterfs/md1/brick1/kvm/hail/hail_home.qcow2 trusted.afr.md1-
client-2=0sAAABJAAAAAAAAAAA trusted.afr.md1-client-3=0sAAAAAAAAAAAAAAAA 
trusted.gfid=0sOCFPGCdrQ9uyq2yTTPCKqQ==  It seems that I have a split-brain. 
How can I solve this issue by resetting the attributes, please ?   Thanks,   Alessandro.
