[jira] [Comment Edited] (HDDS-5664) [FSO] Allow existing/old buckets with any layout during OM startup

[~zhengchenyu] since basic sub-tasks are in and multiple buckets with any layout can co-exists in a single OM, now. I'd like to take this ahead to completion. Kindly update the PR. Thanks again!

> I have a ozone cluster, prefix is enable when setup cluster. when restart om, then error below:
> {code}
> java.io.IOException: Failed to start OM in PREFIX layout format as existing bucket has a different layout SIMPLE metadata format
> {code}
> This issue is similar to HDDS-5094. Later in  HDDS-5362, bucket layout is supported, then addFSOptimizedBucketDetails is removed in this https://github.com/apache/ozone/commit/7df192530810a07d3b976c3a56c46328c0b1d591. So om crash when restart if layout is PREFIX.
> I think there is no need to validate bucket type since HDDS-5362.
