insmod Error inserting `/lib/raid456.ko` -1 File Exist

[Saed]

hi every one ,
Wondering if any of you experienced this During "Centos5.6" Boot .. !

1)NOT USING MMCONFIG
2)insmod Error inserting `/lib/raid456.ko` -1 File Exist

Dell PowerEdge T110 with 4sata Controllers with Centos2.6.18-238.9.1.el5xen installed .

/boot on /dev/md0
/  on   /dev/md1

Regards

That usually means that the module is loaded.Have you checked with "lsmod|grep raid456"?

[Saed]

hello Siddly ,
yes my friend i`ve checked it ..

lsmod | grep raid456

raid456               151137  1 
xor                    39377  1 raid456

i found a thread mentioning the issue
https : // bugzilla.redhat.com/show_bug.cgi?id=512892
but still cant figure how to eliminate it "specifically rebuilding the initrd"
Thanks Siddly..

Well, that's the QA of Red Hat.

The URL said the bug couldn't be found, but I can't see your problem.
It's automatically loading the module as I thought. If that's not the module you want, i.e you have built an updated module you want to use instead, replace the module of the same name in /lib/modules/`uname -r`/kernel/drivers/scsi with your own and run "depmod -a", then reboot.

i`v checked the /etc/sysconfig/modules/ and tried to remove is with the help of this URL
http: //docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sec-Persistent_Module_Loading.html
but i`m not sure where to place the code

#!/bin/sh
if [ ! -c /dev/input/uinput ] ; then
        exec /sbin/modprobe uinput >/dev/null 2>&1
fi

replace the module of the same name in /lib/modules/`uname -r`/kernel/drivers/scsi with your own and run "depmod -a", then reboot.

i`d like to know how to proceed with this approach , can u explain a little bit more plz
Thanks my friend

Give me some more information about what you are trying to do. From my reading of the situation you described:-
The existing raid456 module is being loaded, but you don't want that.
Instead you have a different or updated raid45 module you want to use instead.

If the above is true the existing raid456.ko module exists in /lib/modules/`uname -r`/kernel/drivers/scsi
You can list it, e.g if your kernel is 2.6.39, "uname -r" (without the "quotes) will return the kernel name.
slipstream:~ # uname -r
3.0.0-rc2-smp
slipstream:~ # ls /lib/modules/`uname -r`
build kernel misc modules.alias modules.alias.bin modules.builtin modules.builtin.bin modules.dep modules.dep.bin modules.devname modules.order modules.softdep modules.symbols modules.symbols.bin source
slipstream:~ # ls /lib/modules/3.0.0-rc2-smp
build kernel misc modules.alias modules.alias.bin modules.builtin modules.builtin.bin modules.dep modules.dep.bin modules.devname modules.order modules.softdep modules.symbols modules.symbols.bin source
slipstream:~ #
As you can see both the above commands return the same information.
Somewhere under /lib/modules/`uname -r`/kernel/drivers there is a raid456.ko module that you need to replace with the new raid45.ko module.
After replacing the module, "depmod -a" will check and enable the module so that when you reboot your new module will be the one used.
There is another way but what I described above is the simplest.

Hello Siddly ,
sorry for being too late , Exams stuff

From my reading of the situation you described:-
The existing raid456 module is being loaded, but you don't want that.
Instead you have a different or updated raid45 module you want to use instead.

well , its by default loads the modules required to read the Disk-array to access the drives , as it reads 2 Raid arrays
/dev/md0 , /dev/md1, it adds the module twice ..
after searching the web , i found that its a known bug for the
mkinitrd-5.1.19.6-68.el5_6.1 version ,
a normal fix of this bug is being told that the mkinitrd should be recreated with

mkinitrd -v -f /boot/initrd.$(uname -r).img $(uname -r)

i tried it but in vain .
a friend of mine , provided me with patch made for a work ground regarding this problem , which was
updating the /sbin/mkinitrd with the following lines

 #only need to add each module once
case " $(eval echo \${$modlist}) " in
        *" $modName "*)
            return ;;
        *)
            eval $modlist=\"\${$modlist} $modName\"
            ;;
    esac

1)after making sure that the grub.conf file is also being updated with the exact kernel image being created with mkinitrd
2) makin sure that the module dosn`t gets add twice
the problem still persists

Somewhere under /lib/modules/`uname -r`/kernel/drivers there is a raid456.ko module that you need to replace with the new raid45.ko module.

this isn`t what i`m trying to do , although i`m not sure if it can resolve the problem.

ive been discussing this problem on another forum , before i try to to post here in this decent site .
if u`d like to have a look please see it on

thanks My Friend I really do appreciate your help..
