       Thanks, Neil.  I guess I'll just tear it down and rebuild.

"Squeeze" is definitely not ready for prime time, and I don't think even

it

supplies kernel 2.6.32 or mdadm 3.1.1.  Oh, well.

I am running mdadm 2.6.7.2-1, and 2.6.7.2-3 is available under my

distro.

Do either of these versions support reshaping an array from RAID5 to

RAID6?

No

quoted

Does any later version?

Yes.


You need mdadm-3.1.1 plus linux 2.6.32.

What are you talking about?

       Referring to what, specifically?

Have you not synced to the online
repository?  I grabbed this out of the Package.bz2 file.

       Of course.  I'm running "Lenny" for an AMD-64.  The output below is
definitely not for AMD-64, and it looks to me like it might be "Squeeze" or
"Sid", not "Lenny".

(Yes, BTW, they should probably have a bug filed to get mdadm 3.1
included before the freeze...)

Yes, it is for Squeeze, if you want the latest bugfixes and security
updates you should seriously consider running debian-testing instead
of stable.  Stable is reserved for 'mature' features.  Testing, as far
as I'm aware, will almost never (and should never if you are paying
attention) cause data-loss, but might occasionally get in to a
situation where something breaks; mostly just during upgrades (but
then that's true of any upgrade).
