 Posted: Fri Jul 02, 2004 4:49 pm Post subject: Dell PowerEdge 1400 SC server |
 |
|
Hi all,
I would like to get gentoo working on our server here... It is currently running RedHat AS 2.1, and Gentoo is installed and updated. The problem is I cannot boot up to the root partition. When the initrd tries mounting the root partition, it fails. I have everything in the initrd except scsi_mod. I am rebuilding the initrd as I write this, but I don't believe that is what is causing it to fail.
Has anyone else set it up on a similar server with (4) 36 GB harddrives setup with striping for 100 GB of storage?
Thanks,
Walter |

I've setup a number of Dell PowerEdge servers running Gentoo, I don't think that particulate model. I do have one running RH 7.2 though I think. Did you compile in megaraid controllers for it? You might need that if you are running a RAID card. That's the normal one for the PowerEdge servers.

Hi,
I do have megaraid; however, when doing lsmod on the RedHat box, it lists scsi_mod. I don't have that for the 2.6 kernel (I know this is a server, but I have had good reliability on my desktop). I edited the busybox configuration and tried putting in scsi_mod, but it never included it, I just have megaraid, adaptec drivers, and some other stuff.
Could you send your initrd, or let me know what you have in it as I think that is the point of failure?

|
|
Hi all,
I was able to bootup to my server with the Gentoo CD (I installed from a RedHat environment, and never actually ran Gentoo by itself until today). It mounted my 'root' partition just fine and it loaded some other modules, but they appear to only be for 1394 and 3COM NIC's.
How do I find out what modules the initrd uses? Will an lsmod do? This is my custom busybox configuration:
| Code: |
STORAGE_MODULES="DAC960 ataraid hptraid pdcraid 3w-xxxx a100u2w advansys aha152x aha1542 aha1740 atp870u BusLogic cpqfc dmx3191d dpt_i2o dtc \

sym53c416 sym53c8xx t128 tmscsim u14-34f ultrastor wd7000 aacraid aic7xxx"
#FIREWIRE_MODULES="eth1394 ieee1394 ohci1394 sbp2"
ATARAID_MODULES="ataraid hptraid pdcraid"
PCMCIA_MODULES=""
USB_MODULES="usbcore ehci-hcd uhci usb-ohci hid usb-storage"
INITRD_SIZE=5000
#BOOT_SPLASH_INITRD="/boot/initrd.bs"
MRPROPER="yes"

I have all applicable scsi modules compiled, and the ones I know I need, compiled into the kernel. Any ideas why this stubborn thing won't detect my root partition?

Hi all,
Since the livecd booted up to my system and I could mount the partitions - can I just copy the kernel, initrd, System.map, and /lib/modules/kernel_directory to my actual install? I have no scsi or raid experience and am not quite sure how our system is setup. The latest kernel I tried was based on the kernel configuration the livecd had in /proc. I don't know what else to do to get the thing to mount the root partition.
The system is running RAID5, through an AMI card.

Hi all,
I had to compile in AMI megaraid support, I had it as a module, not built-in. That was all the difference, thanks to the guy at Dell.
