Cool enhancement for this.
But just one thing to confirm, actually rocketmq will delete commit log
when the disk space is ready to be full(85% by default) even though the commit
log file is not expired, won't it @lizhanhui

> Key: ROCKETMQ-27
> URL: https://issues.apache.org/jira/browse/ROCKETMQ-27
> Project: Apache RocketMQ
> Issue Type: New Feature
> Components: rocketmq-store, rocketmq-tools
> Affects Versions: 4.1.0-incubating
> Reporter: Zhanhui Li
> Assignee: vongosling
> Fix For: 4.1.0-incubating
>
>
> RocketMQ broker stores all messages before they are expired, which requires
> pretty much storage for a high load system. For now, the message store can be
> configured to use only one partition. Quite often, we find broker runs out of
> storage as business expands quickly. Online resizing a partition most of time
> is not possible(with absence of LVM) whilst attaching a new disk/partition in
> cloud environment is super easy.
> It would be nice for RocketMQ to be capable of adding extra commit log store
> path online, allocating commit log files onto partitions based on
> free/available space.
