unable to load MDADM module BUT mdadm works?!?!?!

Hi all,

I am running Kernel 2.6.21. When I enter the command:

Code:

root / Server 1# modprobe md
FATAL: Module md not found.

but I can easily run MDADM:

Code:

root / Server 1# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [multipath] [faulty]
md0 : active raid1 sdb8[1] sdb7[0]
      18563008 blocks [2/2] [UU]

unused devices: <none>

Why is that? I looked in folder: /lib/modules/2.6.21.7-hrt1-WR2.0bl_standard/kernel/drivers/ but there's no module named "md"...

modprobe shows only md4.ko module is loaded. Is this the correct module? Why can't I find module md anymore?

Code:

root / Server 1# modprobe -l | grep md
/lib/modules/2.6.21.7-hrt1-WR2.0bl_standard/kernel/crypto/md4.ko

Thanks

'md' is probably built into the kernel rather than as a module:

fgrep CONFIG_MD /boot/config-$(uname -r)

Thanks for the reply. That's probably right.

I can't see anything in my /boot though. I'm running as root:

Code:

root / Server 1# fgrep CONFIG_MD /boot/config-$(uname -r)
fgrep: /boot/config-2.6.21.7-hrt1-WR2.0bl_standard: No such file or directory
