hi
i m trying to install centos5 on my poweredge 2950 with no luck. the raid controler is LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)
indeed all is going fine during the installation but when i reboot the server panic
the first error i got is this one error mounting /dev/root on /sysroot as ext3: block device required
it seems that it can't find the /dev/root devices.
but when i boot in rescue mode the / partition is found without any problem. i can chroot in it
i have tried with 5.5 and 5.4 x86_64 but i always got the problem.
i m really stuck with that :(
Does someone has an idea of what could happened?

I don't know for a 2950, but for a PE 1950 I have : alias scsi_hostadapter megaraid_mbox in /etc/modprobe.conf, and :
$ modinfo megaraid_mbox filename: /lib/modules/2.6.18-194.11.1.el5/kernel/drivers/scsi/megaraid/megaraid_mbox.ko version: 2.20.5.1 license: GPL description: LSI Logic MegaRAID Mailbox Driver
$ rpm -qf /lib/modules/2.6.18-194.11.1.el5/kernel/drivers/scsi/megaraid/megaraid_mbox.ko kernel-2.6.18-194.11.1.el5
Good luck,

We have a 2950 with a Perc 5/i controller running nicely, showing the same modinfo output.
[root@XXXXXXXX ~]# dmesg | grep LSI scsi0 : LSI Logic SAS based MegaRAID driver [root@XXXXXXXX ~]#

well i have discovered that i have exactly the same hardware and it works like a charm :( that s really puzzling.
perhaps a bad firmware update it seems like during the boot it can't see the disk :(

Does the PERC controller know that the drive you want to boot off of is bootable? Have you <ctrl-r>'d into the controller before boot, and then gone to control (there's virtual disks, PD, and the third thing, I forget exactly what it's called, but I'll be able to tell you later today), and down on the bottom, just to the right of center, it displays the bootable drive. Though it doesn't *look* like it, if you tab down there and down arrow, it will display choices....
Oh, and you did note that no matter how you set it up, it *ALWAYS* wants slots 2 & 3 to be RAID group 0, and the drives in slots 0 and 1 to be group 2?
Oh, yes, and it also *REFUSES* to display any drive that's not raided, even if you want your boot and root on a drive that's not raided....
I decided Friday that this *thing* was designed and signed off on by two-toothed idiots with IQs around 57, decended from generations of the same who couldn't manage to run a farm, whose ancestors came to the US by selling themselves as indentured servants, who once they were here were *fired* because they were too stupid to follow directions....
mark "would you like me to *really* tell you how I feel about them?"
well yes the drive is bootable as i can boot from it it s when the kernel need to find the root device that it s the problem it s like it can't find the volume group

well i transfer the initrd on another computer and i can see the megaraid_sas module.
another strange when i install with DVd it works like a charm :( but i would like to install my server with cobbler with all the task in my kickstart done. that s really very very strange
during the boot process the disk are reckoknized as the system can say that the swap partition in on /dev/root/LogVol01 but it says that /dev/root/LogVol00 where is the root partition has no block device. i rerun the mkinird while booting in recue mode but i got the same result. the nash script seems ok i guess the problems is that the lvm is not correctly detected
