- On baremetal setups, if you have `MINIO_VOLUMES="http://minio{1...2}/data{1...4} http://minio{3...4}/data{1...4}"`, you can remove the first argument `http://minio{1...2}/data{1...4}` to update your `MINIO_VOLUMES` setting, then restart all the servers in the setup in parallel using `systemctl restart minio`.

func registerDistErasureRouters(router *mux.Router, endpointServerPools EndpointServerPools) {

	registerStorageRESTHandlers(router, endpointServerPools, globalGrid.Load())

	registerPeerRESTHandlers(router, globalGrid.Load())

## Creating a hotfix branch

Customers in MinIO are allowed LTS on any release they choose to standardize. Production setups seldom change and require maintenance. Hotfix branches are such maintenance branches that allow customers to operate a production cluster without drastic changes to their deployment.

even if compression is enabled for all types.

## To test the setup

To test this setup, practice put calls to the server using `mc` and use `mc ls` on
the data directory to view the size of the object.

successful login, the user is redirected back to the MinIO console. This redirect URL is specified as a parameter by MinIO when the user is redirected to the OpenID Provider in the beginning. For some setups, extra configuration may be required for this step to work correctly.

For a simple setup where the user/client app accesses MinIO directly (i.e. with no intervening proxies/load-balancers), and each MinIO server (if there are more than one) has a unique domain name, this redirection should...

Yes, MinIO will try to transparently migrate any existing IAM data and either stores
it in plaintext (no KMS) or re-encrypts using the KMS.

> Is this change backward compatible? Will it break my setup?

This change is not backward compatible for all setups. In particular, the native
Hashicorp Vault integration - which has been deprecated already - won't be
supported anymore. KES is now mandatory if a third-party KMS should be used.
