test of rolling-restart using rest api

[schose]

Hi all,

We want to test if a cluster bundle on cluster manager needs to restart the cluster peers using the REST API. 

In the first step we run a POST against:

https://CLM:8089/services/cluster/manager/control/default/validate_bundle?output_mode=json

check-restart=true in body

and check for json.entry[0].content.checksum to get the checksum of the new bundle. If there is no checksum, there is no new bundle.

Second we check the checksum against GET:
https://CLM:8089/services/cluster/manager/info?output_mode=json

json.entry[0].content.last_validated_bundle.checksum
json.entry[0].content.last_dry_run_bundle.checksum

to verify if the bundle check and test of the restart is completed and consider

json.entry[0].content.last_check_restart_bundle_result

if the restart is nessary or not. Unfurtunatly we see that the value of  json.entry[0].content.last_check_restart_bundle_result changes, even if last_dry_run_bundle.checksum and last_dry_run_bundle.checksum are set to the correct values.  

to make a long story short we see that the red value is changing, while green is not changing. which is unexprected for us.

tested against v9.2.5 and v9.4.1. At the moment is looks like a timing issue for me and i want to avoid sleep() code. 

Is there a more solid way to check if restart is necessary or not? 

best regards,

Andreas
