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

«Дергай ручки и проверяй в LiveCD».

Для HP b120i дрова подсовываются через inst.dd и флешку с дровами.

про НР много исписано, про данный сервер нет. Однако выбор режима контролера явил диски. ESRT2 сменил на RSTe!

Я тебе про то, что b120i это какой-то там интеловый рейд. Скорее всего дрова подсовываются аналогично. Внутри образа пакет, он ставится перед запуском установщика.

Add RAID driver during install —

All —
I need to add the LSI drivers for the 9750 RAID controller during the install. These drivers are not included in 10.04 (or 10.04.1) and I need to install onto the RAID device I’ve created. LSI provides the drivers and instructions here —

Here are my steps, with the drivers on a USB drive —

There are no errors, but after I reboot I just get «GRUB» in the upper left corner, nothing else.

Re: Add RAID driver during install —

I haven’t been able to get it to work either.

From LSI’s website http://kb.lsi.com/KnowledgebaseArticle14546.aspx
«Linux kernels 2.6.33 and newer include native support for the 3ware 7000/8000/9500S/9550SX(U)/9590SE/9650SE/9690SA/9750 series controllers.»

I was able to download a ubuntu 9.10 x64 ISO from 3ware and install using it.

On a side note I was actually trying to get either FreeNAS or Openfiler installed on the card and neither worked so I tried Ubuntu. At least this gets me working although managing each service individually is a pain (NFS, ISCIS, ect.). Hope that helps.

Re: Add RAID driver during install —

tregora: To fix your GRUB error, just re-install grub either before rebooting into the OS after installation, or while booted into a rescueCD.

Say your installation was on /dev/sdg, / was on sdg2 and /boot was on sdg1, you’ll want the following mounts:

mount /dev/sdg2 /target
mount /dev/sdg1 /target/boot
mount -t proc none /target/proc
mount —bind /dev /target/dev
mount -t sysfs none /target/sys

Then chroot into target:

chroot /target /bin/bash

Then reinstall grub
grub-install /dev/sdg

Obviously, replace sdg with the correct drive for your install.

AMD RAIDXpert driver as DKMS package

Many AMD mainboards for the AM4 socket based on the following chipsets come with RAID support:

But this RAID mode, which needs to be set in the BIOS, requires a specific driver for each OS. There is a driver for Windows, but for Linux AMD provides either a binary blob or the sources. When following the instructions, you will need to recompile the driver and install the kernel module on each kernel update and/or upgrade. Since we are in the 21 century and we have software like DKMS, we don’t need to do this manually, but let it happen automatically.

Therefore we try here to keep the code alive for many kernel versions as possible and deliver it within a PPA for Ubuntu as a DKMS package.

• This will compile sources and install package for current running kernel. If you need to make package for different kernel then you can use KVERS option. After installing edit /etc/mkinitcpio.conf and add

Note: If you just planning on switching to rcraid, my advice is: don’t. Support from AMD for Promontory raid on Linux is pretty much non-existent. You will be way better off sticking with mdadm, zfs or lvm.

If you REALLY want this to dual-boot Linux/Win, also don’t. Setting up virtualization with KVM with GPU Passtrough today is really simple, and you will not need to boot Windows directly on your hardware ever again.

Sidenote: If you decide to use rcraid regardless you might want to also install RAIDXpert. Web interface isn’t working properly on Manjaro, but rcadm is more or less is.

Sidenote 2: If you ever decide to switch from rcraid to something else, you may find it useful to know that deleting arrays only removes metadata. Partitions are still there, and can be recovered with gdisk, gpart etc. I found out that offset for partitions is 1069056 sectors (512B). So if you have partition starting at usual 2048 it will be at 1071104 after array deletion.

Raid driver ��� linux

Where can I get the downloads for the Linux AMD storage RAID driver and the AMD RAIDXpert2 Management Application for the ThinkStation P620? Three different Linux installation documents (RHEL, Ubuntu, and Debian) for the ThinkStation P620 references a download for the driver and a separate download for the RAIDXpert2 Management Application. I cannot find the Linux downloads on the Lenovo support site. The documentation shows the download for the is RAIDXpert2 Management Application is L5RAU02US14WSUSI. I’m looking for the Ubuntu and RHEL downloads if they are separate for each distro. Thanks in advance.

The Linux drivers for the new ThinkStation P620 platform should be posted to the Lenovo Support Site soon, likely by the end of the week.

Re:Linux AMD storage RAID driver and RAIDXpert2 Management Application for the ThinkStation P620

I’m trying to install Ubuntu Server 20.04 on my ThinkStation P620 with the Lenovo AMD driver but it seems that it doesn’t match the Ubuntu kernel:

rcraid: version magic ‘5.4.0-26-generic SMP mod_unload’ should be ‘5.4.0-65-generic SMP mod_unload’

Could you please post a new driver version compiled for the current Ubuntu kernel?

Re:Linux AMD storage RAID driver and RAIDXpert2 Management Application for the ThinkStation P620

Yes, we are aware that the newer versions of the Ubuntu 20.04 kernel (20.04.1 and 20.04.2) doesn’t seem to be working with the current AMD RAID driver, but the original Ubuntu 20.04 image does. Our Linux team is working with AMD on this now.

Re:Linux AMD storage RAID driver and RAIDXpert2 Management Application for the ThinkStation P620

I managed to install the driver and management software on an Ubuntu 20.04.2 (with kernel 5.4 though) after the installation of the OS and it was an absolutely terrible experience. It leaves me with a really bad impression on the Linux support of Lenovo, especially after spending so much money on a workstation.

— Having to build the kernel modules myself and having a bunch of shell scripts for the installation is just a horrible user experience. why is there no repository like for every other bit of Linux software?

— Not having signed kernel modules that require disabling secure boot just doesn’t seem professional and may not even be an option for some people.

— Having to install the driver during the installation of the OS as the only documented option is really not OK. People that add HDDs later will have to setup their entire environment again. Also: I managed to manually install the whole thing after the fact so I don’t really see why this is not supported.

— If I forget to manually rebuild the module after a kernel update, the system will probably not boot. If you have your OS on a RAID array I do not see a way to escape the situation and your data will be probably be lost forever (maybe have a live usb stick and the driver). This is why dkms was developed.

— And while I am ranting: Why is there no option of 4x PCIe 4.0 SSDs when buying the Workstation.

That was my rant, on the positive side I get 9GB/s read speeds on 4xPCIe 3 SSDs, which is great. I hope this serves a documentation for other people that come across this post and as a pointer to the developers of the Linux driver.
