I need guidance to reinstate my Elastic cluster.
I had bootstrapped Elastic Cluster and had created 1 super-user and 2 other system-users too.
Ingest, Data, Gateway nodes had also joined the cluster.
Later, I felt I want to rename the Data but Google-Cloud does not allow me to rename so I created new data nodes with proper name and then deleted the old data nodes.
I had not ingest any data so far, no index was created .
Now, when I tried to see any of the cluster details ( say license information).
It does not authenticate any system user.
I tried re-creating the Bootstrap password and setting again. But that did not work either.
I'm seeing below exception in Elastic logs.
failed to retrieve password hash for reserved user [username]
org.elasticsearch.action.UnavailableShardsException: at least one primary shard for the index [.security-5] is unavailable
Please suggest me, there is a way to reinstate the existing configurations or how can I bootstrap it again .
I had the sudo access, I created a system user using file based auth then re-created other system users with the same password then reverted the access type to normal login That worked for me.
