 Posted: Fri Feb 10, 2006 2:12 am Post subject: Soft RAID issues [SOLVED] |
 |
|
I installed Gentoo on to a desktop machine on a plain old IDE hard drive. Alongside that drive are two SATA drives hooked up on my Intel ICH7R RAID controller, they are set to one part RAID0 and one part RAID1. On initial installation I focused only on getting the system up, and avoided trying the RAID stuff. When everything came up, there was nothing I could do to get the /dev/mapper/ directory to show anything other than controller, which is what the guides say is the result of everything not working right. In the process of trying to get it working right I sorta screwed up the kernel I had without making any backups, so my kernel settings are now possibly entirely wonky. I popped in the install CD again more recently and started using the command "gentoo dodmraid" and when it came up there were my three drives. I was told that the boot CD uses the genkernel so I emerged that and followed the instructions to install it. Unfortunately booting with that causes pretty much the same effect as with my own build. Now I'm getting funky errors from other stuff because I screwed up the kernel again. This kernel madness is driving me crazy. Does anyone think they can help?
Thank you,
Stephen

Screwing up the kernel? If you could break up the text in steps with proper descriptions of all errors and how you set up the RAID array it would be much more understandable. Please do so...

It's little difficult to do that, mostly because I can't get on the 'net when I'm under Gentoo... because I screwed up the kernel. The error there is something along the lines of: Kernel Panic: [something is wrong with] IOMMU. That's what I get when I try to do ifconfig to give it my ip or netmask, or even just "up" it.
It's also very very difficult to say what I tried to get the RAID working, seeing as I tried a lot of thing. The important part is that I'm using the genkernel, and I've installed dmraid from a snapshot (version... 9? I think.) I broke the kernel by doing something to it (I have no idea what) that made it impossible to boot, something to do with mounting the drive that Gentoo was installed on. I'm thinking about starting this all over.
I guess my real question here is, what does "gentoo dodmraid" do? Other than select a couple of kernel options (which ones?) what else does it do to the configs at livecd boot? If I can figure that out, I think I can mount the drives.
(btw, I care about all of this bios RAID crap because this is a dual boot machine... sort of)
Thank you,
Stephen |

| dmraid is for software raid not for hardware raid. Did you compile in support for your Intel RAID controller? If not you will never see the logical devices that the controller presents to the OS. |

Right, the Intel RAID controller on my board is a BIOS RAID, and supported by DMRAID. I'm fairly certain DMRAID is how my controller is done. Yes, I compiled in support for the ICH7R.
Thank you,

Ok, so maybe some more information is in order here:
This is a case where I can't figure out what's going wrong because nearly everything seems to be going right.
I used smartmontools and got this:

When I do the same for /dev/sdb I get an identical report, therefor, it looks like the os is having no trouble with the SATA drivers. Also, I emerged dmraid, and that looks fine.

So I don't think there's any problem with the hardware (plus it works in windows.)
But try as I might, I'm still not seeing anything in /dev/mapper. Are there any suggestions?
Thank you,
Stephen |

Ok, I got some response. It was something to do with kernel modules, though I'm not certain what, and now I have the raid device blocks in /dev/
But I'm still not done. I was able to mount the striped section of the raid, but the mirror section gave me a strange error:
| Code: | ERROR: device-mapper target type "mirror" not in kernel
ERROR: dos: reading /dev/mapper/isw_behebjiaie_MIRROR[No such file or directory] |
I have RAID1 and RAID2 compiled into the kernel, just the same. Any thoughts?
Thank you,
Stephen |

Are you using pseudo-hardware RAID (dmraid)? You'll need this then: | Code: | Device Drivers --> Multi-device support (RAID and LVM)
[*] Multiple devices driver support (RAID and LVM)
<*> Device mapper support
<*> Mirror target (EXPERIMENTAL) |

Perfect! Thank you, it's working now.
