node1:
getfattr -d -m . -e hex /local/
# file: local/
trusted.afr.vol-replication-client-0=0x000000000000000000000000
trusted.afr.vol-replication-client-1=0x000000000000000000000001

getfattr -d -m . -e hex /local/howareyou
# file: local/howareyou
trusted.afr.vol-replication-client-0=0x000000000000000000000000
trusted.afr.vol-replication-client-1=0x000000000000000100000000

node2:
getfattr -d -m . -e hex /local/
# file: local/
trusted.afr.vol-replication-client-0=0x000000000000000000000001
trusted.afr.vol-replication-client-1=0x000000000000000000000000

getfattr -d -m . -e hex /local/hello
# file: local/hello
trusted.afr.vol-replication-client-0=0x000000000000000100000000
trusted.afr.vol-replication-client-1=0x000000000000000000000000
