Добрый день.
Столкнулся с такой проблемой, при подключении дисковой полки по интерфейсу iSCSI, Linux создает только /dev/sg9, а блочное устройство sd не создается. Подскажите, в чем может ошибка и как ее решить?

lsblk - нет команды

есть следующее

Нашел загвоздку, слишком большой размер раздела пытался примапить 5Тб.
Для теста отдал кусок в 100Гб и все получилось.
