У меня есть сервер Dell с подключенным к нему хранилищем Dell с настройкой многолучевого распространения. Специалисты Dell оставили сервер с установленной Red Hat 7 на внутреннем диске (/dev/sda) и подключенным диском к хранилищу в /dev/mapper/DB_DATA01 .
Все работало нормально, за исключением двух путей к внешнему хранилищу, которые также рассматривались как /dev /sdb и /dev /sdc.
Тогда я совершил ошибку: запущенный parted , чтобы создать gpt таблицу в / DEV / SDB вместо /dev/mapper/DB_DATA01 После того, как я это сделал, я правильно создал и отформатировал раздел xfs внутри /dev/mapper/DB_DATA01 , правильно настроил инструкцию монтирования в /dev/fstab . Затем я перезагрузился.
Теперь, каждый раз, когда я перезагружаю сервер, он запрашивает режим обслуживания, говоря, что он не смог смонтировать /dev/mapper/DB_DATA01 в точку монтирования /db2 . Но, если я нажимаю CTRL +D сервер запускается нормально, и все работает ...
Как я могу исправить этот беспорядок и сделать запуск сервера без запроса на обслуживание?
Я знаю, что где-то есть неправильная конфигурация. Кстати, вот выходы, которые у меня есть на данный момент:
