currently we have glusterd/logs  under /etc , we need to move log files to /var/log 

#ls -l /etc/glusterd/
total 20
-rw-r--r-- 1 root root   42 Sep 28 02:47 glusterd.info
drwxr-xr-x 3 root root 4096 Sep 28 02:49 logs
drwxr-xr-x 3 root root 4096 Sep 28 05:43 nfs
drwxr-xr-x 2 root root 4096 Sep 28 03:24 peers
drwxr-xr-x 3 root root 4096 Sep 28 02:49 vols

apache log setup -

#ls -l /etc/httpd/
total 8
drwxr-xr-x. 2 root root 4096 Sep 15 18:32 conf
drwxr-xr-x. 2 root root 4096 Sep 15 18:32 conf.d
lrwxrwxrwx. 1 root root   19 Sep 15 18:32 logs -> ../../var/log/httpd

Now '/etc/glusterd/logs' points to '{$prefix}/var/log/glusterfs/'
