rsyslog and sshd don't start after mounting /var in a new disk

Issue

• sshd does not start with selinux in enforcing mode.

• A new hard drive was added to the system and mounted /var on it.

Contents of original /var were copied to new /var  and after that rsyslog and ssh don't start

#/etc/init.d/rsyslog start

Starting system registry manager: Can't open or create /var/run/syslogd.pid
Can't write pid.

#/etc/init.d/sshd start

Starting sshd: Missing privilege separation directory: /var/empty/sshd
