Re: Triple parity and beyond

Hi Piergiorgio,

In RAID-6 (as per raid6check) there is an easy way
to verify where an HDD has incorrect data.
I suspect, for each 2 parity block it should be
possible to find 1 error (and if this is true, then
quad parity is more attractive than triple one).

Yes. The theory say that with quad parity is possible to find 2
errors. Or find 1 error when running in degraded mode with 2 missing
disks.

But yep, the problem is how to do in a fast way. I don't know enough
the field to answer this.

Ciao,
Andrea
