>
> 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..
