Корневой раздел, в четыре раза больше, чем, я указал
Я выполняю Сервер Ubuntu 18.04 с дисками на 4x2 ТБ в набеге программного обеспечения 0. На веб-странице установки панели OS я указал 4 раздела, / начальная загрузка 500 МБ, корень 15 ГБ, подкачка 4 ГБ и / домой со всем остальные. Однако корневой раздел, кажется, составляет 60 ГБ вместо 15 ГБ. Любая справка значительно ценилась бы.

у вас 4 диска и raid0, = 4 * 15 = 60 ГБ.
lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT
показывает, как распределяется /root на ваших 4 дисках.
Чтобы получить 15 ГБ, нужно выбрать 3,75 ГБ.
