*На "Percentage Used: 134%" стоит Debian + nginx + php-fpm + mariadb + postfix(т.е. основной почти сдох - как? Он работает от силы 1,5 года), а на "2% использования" находятся ~250 сайтов(только их файлы, картинки).
Собственно вопросы:
1) была ситуация кода "/dev/nvme0n1" и "/dev/nvme1n1" данные поменялись местами. Это нормально?(при этом после перезагрузки всё в порядке было)
2) Я вижу "Percentage Used: 134%". Как такое возможно и как выяснить: откуда это?
Сложный
