Hi, I have a Vault Cluster with Integrated Storage and Auto-Unseal configured.
This cluster is running in VMware with Ubuntu 22.04 as host OS.
For now, it is running on version 1.14.0 and I wanted to upgrade it to latest 1.15.5.
Therefore, the normal upgrade procedure would be to replace the binary and reboot one node after the other. As I have Auto-Unseal in place, this failed miserably.
The Vault service will not start anymore as it is sealed after restart. Auto-Unseal is not working and unfortunately, I cannot unseal it.
I am relatively new to Vault. Has someone experiences with a scenario like this and might be able to help me out here?
Thanks in advance.
