Изменение размера цифровых капель океана, использующих CoreOS, разрушает кластер CoreOs

Я новичок в CoreOs, и я экспериментировал с ними на DigitalOcean. Позвольте мне начать с того, что я не уверен, проблема ли это DigitalOcean или проблема CoreOS.

Как воспроизвести:

• Разверните 2 CoreOS и свяжите их вместе, чтобы сформировать кластер через Cloud-Config.
• На панели Digital Ocean Dashboard отключите обе капли и измените размер.
• Включите обе капли.
• ssh в одну из капель
• запустить fleetctl list-machines

Это проблема с CoreOS? Практически весь кластер CoreOS сломан. Машины больше не связаны, и я, кажется, не могу придумать способ связать их обратно или как предотвратить это. Я ничего не могу найти об этом в Интернете.
