Вырубаем сервер, втыкаем дополнительный винт, включаем, понеслось, более суток новый винт вливался в общее пространстово 5 рейда.

Для наглядности sysinstall --> fdisk смотрим:

Видим что у нас появилось свободное место после нашего слайса s1, копируем последний сектор(3750067967) идем дальше

Нужно отмонтировать все разделы с данного жеского диска и проверить их на ошибки fsck.

Дальше fdisk`om поправляем размер как видит его система.

Смотрим что получилось

Поправляем размер партиции на наш новый "3750052887":

ftp# bsdlabel -e /dev/da0s1 # /dev/da0s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 3750052887 0 unused 0 0 # "raw" part, don't edit d: 3750052887 0 4.2BSD 2048 16384 28552

Хотя там и написано "raw" part, don't edit" надо в обеих строчках поменять размер.

Ждем пока все пробежит и потом ещё достаточно долгое время в тишине, но не паникуйте, growfs работает, просто молчит. ----------------------------------------

*Важное примечание: growfs не может работать с разделами дисков больше 2Тб.

Далее делаем нашему растянутому разделу fsck -y
и можем смело монтировать.
