Cluster Upgrade failure

[vishal_shenduri]

Hi All,

We are receiving the below error message while upgrade the cluster node and it's not updating so if anyone seen the same error message while upgrading? or any solution to this?

Error: Nodekeeper was not upgraded successfully, reason: Nodekeeper upgrade failed on host cluster_IP due to: Script has returned code 0 with status OK and with details: 2023-08-12 05:22:55 UTC 0 Starting Dynatrace 1.260.197.20230516-071927 installer ... 
2023-08-12 05:22:59 UTC 100 Upgrade of nodekeeper failed 
FAILED 
IP address cluster_IP used in previous installation doesn't belong to this machine anymore. 

cluster_IP - replaced with cluster IP

Thanks in advance

Has the IP of the machine changed between the previous installation/update and this one?

Hi,

Such a situation usually arises when expanding the cluster with new nodes when the first node is cloned. When performing an update, this error is very strange.

The best solution in this case will be to open a ticket in support.
