we tried setting the array itself read only,
which prevent (or it should) anybody above,
filesystem or LVM, to perform writes...
Neveretheless, the result was a bit "strange",
namely a kernel BUG() or similar, we had to
reset the PC.
I'm not sure if this was caused by other issue,
since the PC was in a not really healty state,
or a direct consequence of md device in r/o.
bye,
