Dear Piergiorgio,

In message [ref] you wrote:

I would shamelessly suggest to try "raid6check", in order
to see if some components have problems.

The software is somehow buried into "mdadm" source code,
probably you'll need to take it from the repository.

Found it.  Thanks for the suggestion.

However, this is extreme verbose:

...

etc. ad nauseam.  I guess "pos" means stripe here, so it would print
this for all stripes in the array?  Does this means all of them are
broken?  Or what would I  have to look for to see where an error
mightbe?

Best regards,

Wolfgang Denk
