I started to work with Minio and I’m doing little POC. I have a problem with simple expanding of exiting pool. I have a pool with one server and one disk. I want to expand my tenant with new pool with 1 server with 1 disk. I do it with GUI with Pools -> Expand Tenant and I’m getting error :

ERROR Unable to initialize backend: /export/data drive is already being used in another erasure deployment. (Number of drives specified: 2 but the number of drives found in the 1st drive's format.json: 1)

I’m working with K8s operator in version: quay.io/minio/operator:v5.0.11
pool-main is exiting pools, and I want to add pool-1
My tenant config:

  buckets:
  - name: os-snapshots
  - name: backups

I want to expand exiting pool.
