Hi

Is there any way to use an MD RAID in write through mode?  I
appreciate that there is a performance impact but this is important
from a security prospective....

The likelihood is that I would use RAID0 (I know this sounds like a
contradiction to the above, but the ‘drives’ are probably hardware
RAIDs).  But may use standard RAID6.

I cannot see any way to disable write cache in MD, but I am hopefully
I am simply missing something obvious.

I appreciate any feedback....

Thanks, Mark
