Hi, Neil...

I use MD driver two year ago with Debian, and run perfectly.

Now, I added our machine to a cluster with kernel 2.4.27 and openmosix
patches. We wish to use the cluster to power our primary machine.

I copied the kernel, modules and initrd from the running cluster to the
machine (openmosix need all nodes with same kernel version).

The machine boot the new kernel a run Ok... but... if I (or another
process) make a change/write to the raid md system, the computer crash
with the message:

hdh: Drive not ready for command.

(hdh is the mirror raid1 for hdf disk).

Is MD driver not openmosix-ware?

Thanks!

I cannot help thinking that maybe the Drive is not ready for the
command. i.e. it isn't an md problem. It isn't an openmosix
problem. It is a drive hardware problem, or maybe an IDE controller
problem. Can you try a different drive? Can you try just putting a
filesystem on that drive alone and see if it works?
