Возникла проблема - на большом рейд 5 массиве закончилось свободное место, забэкапить куда-либо 1.5ТБ данных не предоставилось возможности.
Внимательно посмотрев на рейд контроллер удалось установить что он умеет в рабочий массив добавлять диски

The following commands are supported (in upper or lower case):
A = Use Entire Disk G = set Drive Geometry C = Create Slice F = `DD' mode
D = Delete Slice Z = Toggle Size Units S = Set Bootable | = Wizard m.
T = Change Type U = Undo All Changes W = Write Changes
Use F1 or ? to get more help, arrow keys to select.
Нужно отмонтировать все разделы с данного жеского диска и проверить их на ошибки fsck.
Дальше fdisk`om поправляем размер как видит его в система.
