Description krishnaram Karthick 2017-08-24 12:54:28 UTC 
Description of problem:
/etc/target/saveconfig.json is introduced as a directory instead of a file in the container image. As a result, target service doesn't come up.

Comment 8 Humble Chirammal 2017-08-24 14:15:59 UTC 
This was an issue in bind mount of /etc/target which is corrected now in the template and next cns-build will have the fix.
Comment 9 krishnaram Karthick 2017-09-01 13:02:41 UTC 
Verified the fix in build - cns-deploy-5.0.0-23.el7rhgs.x86_64

gluster-block-target service starts without any issues and the configuration file is stored in /etc/target/saveconfig.json

sh-4.2# ls -l /etc/target/saveconfig.json
