unable to continue installation after failure

[poligraph]

if any error occurs during gk-deploy command it's unable to re-run command again

for example, if I run second time ./gk-deploy -g --admin-key 123456 --user-key 123456

I will get following error and I don't know how to continue installation.

This may indicate that the storage must be wiped and the GlusterFS nodes must be reset.

You could comment out section in the gk-deploy script that does all the steps that have been successful in your case and re-run from line 875: eval_output "${CLI} exec -i ${heketi_pod} -- cat /tmp/heketi-storage.json
