Подробные данные о диске на Debian 7, 8, 9, 10 и прочих ОС
Программа работает для стандартных SATA и SSD дисков. Для NVME дисков мануал здесь.
Ставим утилиту для Debian и Debian подобных ОС:
Для CentOS:
Вводим команду на список дисков:
Будет:
Вводим команду на диск /dev/sda:
И получаем данные о диске:
Также можно сейчас можно знать информацию и NVME дисках через smart.
NVME диски имею маркировку: nvme0n1… nvme1n1 и так до nvme*n1. Список дисков всегда можно достать командой fdisk -l.
Например смотрим инфу по NVME:
Ставим утилиту для Debian и Debian подобных ОС:
apt-get install smartmontools
Для CentOS:
yum install smartmontools
Вводим команду на список дисков:
fdisk -l
