> The parameter of {{BlockPoolSliceStorage#removeVolumes()}} is a set of volume level directories,
thus {{BlockPoolSliceStorage}} could not directly compare its own {{StorageDirs}} with this
volume-level directory. The result of that is {{BlockPoolSliceStorage}} did not actually remove
the targeted {{StorageDirectory}}.
> It will cause failure when remove a volume and then immediately add a volume back with
the same mount point..
