В одном из обслуживаемых серверов, согласно выводу dmesg, установлен RAID-контроллер Adaptec, который FreeBSD распознала как aac0. Выборка из dmesg:
# cat /var/run/dmesg.boot | grep RAID aac0: Adaptec RAID controller, aac driver 2.1.9-1 aacd0: <RAID 1 (Mirror)> on aac0 |
Для работы с этим контроллером воспользуемся возможностями утилиты arcconf. Arcconf - утилита для работы с контроллерами RAID из командной строки. С ее помощью можно получить детальную информацию о контроллере и созданных массивах.
Установку, как всегда, выполним из системы портов:
# cd /usr/ports/sysutils/arcconf && make install clean && rehash |
Размер дистрибутива "порадовал" - 99 MB. Хорошо, что сервер отдавал дистрибутив на скорости около 20 Mbps. А установка вообще заняла несколько строк. Собственно:
# cd /usr/ports/sysutils/arcconf && make install clean && rehash => asm_freebsd_x86_v7_30_18837.tgz doesn't seem to exist in /usr/ports/distfiles/. => Attempting to fetch http://download.adaptec.com/raid/storage_manager/asm_freebsd_x86_v7_30_1... asm_freebsd_x86_v7_30_18837.tgz 100% of 99 MB 2641 kBps 00m00s ===> Extracting for arcconf-v7.30.18837 => SHA256 Checksum OK for asm_freebsd_x86_v7_30_18837.tgz. ===> Patching for arcconf-v7.30.18837 ===> Configuring for arcconf-v7.30.18837 ===> Installing for arcconf-v7.30.18837 ===> Generating temporary packing list ===> Checking if sysutils/arcconf already installed install -s -o root -g wheel -m 555 /usr/ports/sysutils/arcconf/work/freebsd8/cmdline/arcconf /usr/local/sbin install -o root -g wheel -m 555 /usr/ports/sysutils/arcconf/work/410.status-aac-raid /usr/local/etc/periodic/daily ===> Registering installation for arcconf-v7.30.18837 ===> Cleaning for arcconf-v7.30.18837 |
После установки утилиты ознакомимся с ее возможностями. Для вывода "хелпа" запустим утилиту без указания ключей:

Проверим состояние массива (он у меня под номером 1):

Как оказалось, один из дисков "вылетел" из массива. Скорей всего кто-то выдернул диск на работающей системе, тоесть "вгорячую". Необходимо пересобирать массив, но это уже тема для отдельной статьи ;)
