Недавно я перезапустил один из узлов cassandra (который является начальным узлом) и получил следующие ошибки, странная вещь в том, что раньше я запускал кластер с токеном, установленным в 256, теперь я получаю «не могу изменить токен»от 512 до 256 "ошибка.

Кто-нибудь испытывал это раньше? Единственное, что я нашел в Интернете, - это когда люди пытаются перейти с vnodes на один токен. И решение состоит в том, чтобы полностью удалить данные и восстановить их из снимка.
