Привет! У нас PVE 8.1.4 и PBS 3.1. PBS зависает на два дня подряд во время резервного копирования. В это же время и сама машина, которую копируют, тоже зависает. Если попытаться перезапустить эту машину, появляется сообщение об ошибке "TASK ERROR: VM is locked (backup)". Если перезагрузить PBS, машина продолжит работать, но диски внутри неё становятся недоступными. После перезапуска виртуальной машины на файловой системе появляются ошибки. Я повторил эту ситуацию на PVE 7.4 и столкнулся с той же проблемой.
