> OzoneContainer won't handle any disk failures before initializing the ContainerSet. In a very extreme case, all the disk are bad and the OzoneContainer can still be running. We can improve this and add disk failure tolerance, like DataNode already did.
> {code:java}
>   private void buildContainerSet() {
>     Iterator<HddsVolume> volumeSetIterator = volumeSet.getVolumesList()
>         .iterator();
>     ArrayList<Thread> volumeThreads = new ArrayList<Thread>();
>     //TODO: diskchecker should be run before this, to see how disks are.
>     // And also handle disk failure tolerance need to be added
>     while (volumeSetIterator.hasNext()) {
>       HddsVolume volume = volumeSetIterator.next();
>       Thread thread = new Thread(new ContainerReader(volumeSet, volume,
>           containerSet, config));
>       thread.start();
>       volumeThreads.add(thread);
>     }
> {code}
