Question Building a Slack server - dual Xeon RAID


Hey..how ya all doing??

I have this sorta problem, well more like that I need some hands-on information from the experts. I have this server, dual Xeon 2.8 on an Intel SE7525GP2 with 2 GB of ram...The board has a built in RAID controler for SATA disks...there are 2 120 GB SATA disks in the machine...as far as I understand it, the RAID controller supports hardware RAID 0 and 1 arrays.

Now, I wanna install Slack 10 on this machine. I'm no linux newbie, but then again I'm no expert either. I've build servers before with linux, just not on such "fancy" equipment. I need some instructions on things to do so that this server will run at its best... the first problem is the image to use to boot the computer?? Should I use a 2.6.x kernel...should I install the system with the default 2.4 kernel that came on the disk, and than recompile and install a 2.6.x highmem enabled kernel? Is this the right way?? As far as I understand Slack doesn't come with a highmem enabled kernel...any things I must be carefull of when recompiling the kernel for dual processor higmem support??

I read in another topic, that with harware RAID there are no OS specific installation procedures for enabling raid...I just set it in the RAID bios and that's it. Is that right??

Thanks in advance for your time and all your thoughts and comments are very appreciated..

Thanks and best regards,

Uros

As to the hardware raid:

Yes just select the raid partitions when installing Slack.

I don't think any of the default Slack kernels have SMP (multiprocessor support) enabled. I'd install using the vanilla Slack kernel and then compile a new 2.6 kernel with highmem and SMP.

dual Xeon

I have not tried the 2.6 series yet, but have spent some time with 2.4.26 Slackware on a dual 2.8ghz Xeon unit.

If you go with that, when recompiling the kernel to get SMP functioning, there are a few things that may help.

In processor type Pentium 4; HIGHMEM = 4 gig; MTTR = y; SMP = y

in General setup, No Power Managment Support; ACPI = y (without this you get only 2 cpu)

ACPI Support, Config ACPI = y; Config ACPI HT Only = y

Character Devices, Enhanced Real Time Clock

There may be other things that you system will require.

Please keep us informed on your progress. I have SCSI stuff on my dual Xeon, and have no experiance with SATA. Yours should nevertheless be a wonderful system.

Hello...me again... with some troubles...oh well..

So, I recompiled the kernel and everything was fine except that I found out that the RAID controler isn't really a hardware RAID controler, but a software RAID controler and I can't get the blody thing to work correctly....

It's supose to be a LSI Megaraid sata 2 controler and the kernel config menu had it listed in the Low Level SCSI somethin...I included it in the kernel, but nothing, nada...as the new kernel booted, there was no output that the thign started.. I compiled it directly in the kernel not as a module... what am I doing wrong??

Does anyone have any expirience with this fake RAID controler?? What should I do...I really would like to get this RAID thing to work...should I just use md instead...

Please help and best regards,

Uros

linux will not recognize for example a stripped set on such a controller.
You'll have to use software raid if you want to use a raid array.
To install slackware using md is a bit complicated.
Other distro's can be installed using md , fedora , Suse.
