Re: RAID-6 ...

Until now I haven't really paid too much attention to the RAID-6 stuff,
but I have an application which needs to be as resilient to disk failures
as possible.

So other than what's at:

  ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/

and the archives of this list (which I'm re-reading now), can anyone give
me a quick heads-up about it?

Specifically I'm still buried in the dark days of 2.4.27/28 - are there
recent patches against 2.4?

There is no current support for raid6 in any 2.4 kernel and I am not
aware of anyone planning such support.  Assume it is 2.6 only.

If RAID-6 isn't viable for me right now, what I'm planning is as follows:

Put 8 x 250GB SATA drives in the system, and arrange them in 4 pairs of
RAID-1 units.

Assemble the 4 RAID-1 units into a RAID-5.

Sounds reasonable.
