CTBD don't start when create soft link on CentOS 7

[GiangCoi Mr]

Hi team.

I have a issue when I configure CTDB with Samba 4 on CenOS 7. This is my
configuration:

----------------------------------------------
vim /data/lock/ctdb

CTDB_RECOVERY_LOCK=/data/lock/lockfile
#CIFS only
CTDB_PUBLIC_INTERFACE=ens32
CTDB_PUBLIC_ADDRESSES=/etc/ctdb/public_addresses
CTDB_MANAGES_SAMBA=yes
#CIFS only
#
CTDB_NODES=/etc/ctdb/nodes
-----------------------------------------------
vim /data/lock/nodes
172.17.4.10
172.17.4.20
-----------------------------------------------
vim /data/lock/public_addresses
10.10.5.92/24 ens32
-----------------------------------------------

I create soft link on file01 and file02

ln -s /data/lock/nodes /etc/ctdb/nodes
ln -s /data/lock/public_addresses /etc/ctdb/public_addresses

after I start ctdb, but it's not running, this is my log.ctdb
