Subject: [d-kernel] Возвращаясь к RAID
Date: Fri, 11 Feb 2005 23:56:00 +0300
Message-ID: <200502112356.00206.shadrinovdd@ystu.ru> (raw)

Раз уж при выключении размонтировать корень невозможно, а корень расположен
на RAID, может быть не стоит выводить сообщение FAILED, а использовать
 проверку оставшихся подмонтированных файловых систем и отрубать только
 те RAID'ы которые не используются? Например так:

--- /etc/init.d/halt    2004-03-04 17:28:34 +0300
