Подсунуть драйвера raid при установке

Доброго! Была такая тема, но сабж в ней так и не раскрыт. имею Intel R1304GL4DS9, для него скачаны Intel® Embedded Server RAID Technology 2 RAID Driver для Linux нужно поднять CentOS 7. как подсунуть драйвера?

Никак, там модули (драйверы), собранные Red Hat 7, 7.1, 7.2, 7.3 и под Suse Linux Enterprise Server 12 и его обновления.

Исходников модуля (драйвера) что бы собрать его под другое ядро (другого дистрибутива) нет.

Поэтому ставь CentOS на RAID программный RAID собранные средствами mdadm.

ну нет. Только что установил на зеркале, без mdadm и никаких проблем. Единственное сервер был посвежее и производитель SuperMicro. полагаю, дело чисто в дровах

На supermicro такой же RAID?

чипсет там другой возможно, но рейд такой же, ну в смысле там тоже зеркало

Я не про зеркало / не зеркало, я про RAID контроллер.

Это неполноценный аппаратный RAID, так что ставь систему на RAID посредством mdadm.

Всё равно даже если ты создашь RAID в оболочке самого RAID контроллера ты увидишь RAID массивы в системе используя mdadm.

систему на RAID посредством mdadm

тут не совсем понял. Я понял что сначала ставим на один винт CentOS, потом устанавливаем mdadm и создаем RAID. нет?

Можно сразу создать массив и на него ставить.

Во время установки создай RAID массив и ставь на него.

подсобите с настройками BIOS, а то установщик не видит диски, только флешку с которой идет установка. «the Redhat recommendation for such things is to disable RAID mode in the controller BIOS and set it to AHCI mode» но в «Intel® Embedded Server RAID Technology II (Intel® ESRT2) uses Ctrl+E to enter the RAID BIOS console.» нет такой фичи как выбрать AHCI mode а в BIOS сервера стоит: AHCI capable SATA Controller=[AHCI] SAS/SATA Capable Controller=Intel(R) ESRT2 (LSI)

Хз, читай документацию к плате, грузись в установщик CentOS или какой-нибудь Linux LiveCD и смотри увидел ли он диски подключенные к контроллеру или нет.

Может эта настройка в «Advanced options» в BIOS (UEFI).

указанные настройки как раз в эдванседе и находятся

Во многих материнках Supermicro есть встроенный софтварный RAID контроллер. Для входя в управление нужно при загрузке нажать Ctrl+I. Но есть ньюанс — управлялка работает только в режиме Legacy. Legacy не поддерживает разделы более 2 Тб, как быть? Расскажу как настроить RAID и для Legacy и в UEFI.

Если вы не планируете разделов более 2 Тб, не заморачивайтесь и настройте загрузку в Legacy.

Legacy

При загрузке жмём DEL и попадаем в BIOS.

В разделе Boot меняем Boot Mode Select на Legacy:

В разделе Advanced выполняем SATA Configuration, Configure SATA as RAID:

Появляются дополнительные пункты настройки. Оставляем SATA RAID Option ROM/UEFI Driver как Legacy:

SATA/sSATA RAID Boot Select меняем на SATA Controller:

Перезагружаем сервер, при загрузке жмём Ctrl+I, попадаем в раздел конфигурации Intel Rapid Storage Technology:

Создаём RAID. Я объединяю 4 диска в RAID0:

Перезагружаемся, снова входим в BIOS. В разделе Boot в FIXED BOOT ORDER Priorities появляется возможность выбрать Hard Disk:Intel RAID0 — наш новый массив:

Можно пользоваться. Однако, если вы, вдруг, попытаетесь поставить Oracle Linux, то в инсталляторе не сможете создать раздел более 2 Тб. Что делать?

Итак, для перехода в UEFi внесём в предыдущую инструкцию некоторые изменения.

Выполняем все инструкции для Legacy и снова загружаемся в BIOS (Продвинутые могут смерджить инструкции и сократить количество перезагрузок). Вносим изменения в Advanced > SATA Configuration. Меняем SATA RAID Option ROM/UEFI Driver на EFI:

В Boot > Boot Mode Select ставим DUAL. Можно, наверное, и просто UEFI, но тогда при перезагрузке не сможете попадать в раздел конфигурирования контроллера:

FIXED BOOT ORDER Priorities становится значительно больше. Двигаем все пункты с EFI вверх.

Теперь можно загружать инсталлятор Oracle Linux в режиме UEFI, он нормально видит RAID и может создать раздел более 2 Тб.

Ура, товарищи! Да здравствует то, во имя чего мы все приложили усилия!

The best way to fix your PC to run at peak performance is to update your drivers. If your system is slow, unresponsive or crashes often, the problem may be with your drivers. Sometimes, after upgrading to a newer operating system such as Windows 10, problems can occur because your current driver may only work with an older version of Windows. To download and update your drivers, follow the instructions below.

Tech Tip: If you are having trouble deciding which is the right driver, try the Driver Update Utility for Gigabyte Technology. It is a software utility that will find the right driver for you — automatically.

Gigabyte Technology updates their drivers regularly. To get the latest Windows 10 driver, you may need to go to Gigabyte Technology website to find the driver for to your specific Windows version and device model.

Step 2 — Install Your Driver

After you download your new driver, then you have to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.

How to Open Device Manager

In Windows 8.1 & Windows 10, right-click the Start menu and select Device Manager

In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose «All Apps» -> swipe or scroll right and choose «Control Panel» (under Windows System section) -> Hardware and Sound -> Device Manager

In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager

In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager

In Windows XP, click Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager button

How to Install drivers using Device Manager

Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.

Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.

If you are having trouble installing your driver, you should use the Driver Update Utility for Gigabyte Technology. It is a software utility that automatically finds, downloads and installs the right driver for your system. You can even backup your drivers before making any changes, and revert back in case there were any problems.

Try it now to safely update all of your drivers in just a few clicks. Once you download and run the utility, it will scan for out-of-date or missing drivers:

When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date. You can update individual drivers, or all of the necessary drivers with one click.

Manage Intel RAID under GNU/Linux using mdadm tool

You may be interesting to read some history about RAID first.
This article is about managing Intel RAID, with mdadm tool, but some information may apply to others kinds.
To begin, you can find lots of information about RAID under GNU/Linux.

IMPORTANT: for Intel’s IMSM support you need at least
version 3.2 of mdadm tool (thanks to Iwan for this information).

Usually, there is a container device (let’s call it /dev/md127 in this article), and the RAID device (let’s call it /dev/md126 in this article).
Instead of long blabla, this article will give some common commands to help manage Intel RAID with mdadm tool.

To report the RAID information from the Option ROM (for instance «Intel(R) Matrix Storage Manager»):
mdadm —detail-platform

To get general details:
mdadm -D /dev/md127

To examine information (including members):
mdadm -E /dev/md127

To assemble the RAID array inside the container, and/or to start it (the -e option declares the style of RAID metadata (superblock) to be used):
mdadm -I -e imsm /dev/md127

To check the current state:
cat /proc/mdstat

Output sample (with a RAID 10 having 4 members):
Personalities : [raid10]
md126 : active raid10 sda[3] sdb[2] sdc[1] sdd[0]
3907023872 blocks super external:/md127/0 64K chunks 2 near-copies [4/4] [UUUU]
[=>. ] resync = 6.6% (258923904/3907024128) finish=305.7min speed=198882K/sec

md127 : inactive sdb[3](S) sda[2](S) sdc[1](S) sdd[0](S)
9028 blocks super external:imsm

To add it to the configuration file (to be activated automagically at boot):
mdadm —examine —scan >> /etc/mdadm.conf

For advanced commands (including repairing), you should read this.
