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 
-rw-------. 1 root root 24696 Aug 29 06:17 /etc/target/saveconfig.json

snippet of gluster-template:

          volumeMounts:
          - mountPath: /etc/target
            name: glusterfs-gblock

Moving the bug to verified.
