Просто запустил обновление apt-get на одном из моих выделенных серверов, чтобы остаться с довольно страшным предупреждением:

В соответствии с инструкциями я проверил выходные данные / usr / share / mdadm / mkconf и сравнил их с /etc/mdadm/mdadm.conf, и они совершенно разные.
Вот содержимое /etc/mdadm/mdadm.conf:

Насколько я понимаю, мне нужно заменить четыре строки, начинающиеся с «ARRAY» в файле /etc/mdadm/mdadm.conf, четырьмя другими строками «ARRAY» из вывода / usr / share / mdadm / mkconf.
Когда я сделал это, а затем запустил update-initramfs -u, предупреждений больше не было.
Правильно ли то, что я сделал выше? Теперь я боюсь перезагрузить сервер из-за страха, что он не перезагрузится, и из-за того, что он является удаленным выделенным сервером, это, безусловно, будет означать время простоя и, возможно, будет дорого запускать его снова.
