Файловая система только для чтения

Я изменил размер раздела (ext4) с Живого CD с GParted, и после перезагрузки он говорит, что файловая система только для чтения.

Я перезагрузил снова с CD и проверил его с GParted без ошибок.
Как я мог узнать, почему это повторно монтирует файловую систему в режиме только для чтения?

править: Это обычно запускается, но через какое-то время, "/" точка монтирования повторно смонтирована с настройками только для чтения, таким образом, я думаю, что это действительно имеет ошибки в конечном счете.
Там какой-либо другой путь состоит в том, чтобы восстановить его?

Если я пытаюсь удалить файл с inode идентификатором. 5636499?
Это - путь файла:

~/.cache/google-chrome/Default/Cache/data_3

(Действительно ли возможно проверить, существуют ли другие файлы как это?)

править: После удаления хромового кэша я не столкнулся с этой ошибкой.
