G'day all,
This message is really just for future googles.
I have been running a 15 disk raid-6 since 24th feb in production and can completely vouch for it's
stability. I have had both simulated and real drive failures and it has handled itself perfectly
under all cases. Unclean shutdowns and resyncs have all been perfect.
I know it's tagged as stable in any case, but I still get E-mails from people dragging my name from
google asking about it, so I place this here for the public record.

Many thanks to hpa and others responsible for raid-6. I have already had a 2 drive failure and they
were so close together even a hot spare would not have had time to rebuild.
Also thanks to Neil Brown for a great monitoring and management tool. Mdadm and it's monitoring to
E-mail has been invaluable.
I'd also like to thank Maxtor for producing drives that actually have useful S.M.A.R.T. data. Wish
the other manuf's would follow suit.
Brad
