Добрый день! На сервере HP DL160g6, подключены два диска Western Digital по 500 GB. Raid контроллер встроенный, но не используется и в bios выбран интерфейс AHCI
После выключения сервера и если я вытащу второй диск, а потом за нового установлю его в hot swap корзину, после mdadm снова начинает делать синхронизацию на второй диск.
В данный момент имеется сервер следующей конфигурации: Debian 6. LAMP+Nginx
Диск разбит на два раздела загрузочный и корневой каталог /boot / Два диска по 500 gb sata, соедененны в Raid 1, программным raid mdadm. ================================================= root@us1:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb2[1] sda2[0] 488188792 blocks super 1.2 [2/2] [UU]
