linux raid faq

linux raid faq

[Keld Jørn Simonsen]

Hmm, I read the Linux raid faq on
http://www.faqs.org/contrib/linux-raid/x37.html

It looks pretty outdated, referring to how to patch 2.2 kernels and
not mentioning new mdadm, nor raid10. It was not dated. 
It seemed to be related to the linux-raid list, telling where to find
archives of the list.

Maybe time for an update? or is this not the right place to write stuff?

If I searched on google for "raid faq", the first say 5-7 items did not
mention raid10. 

Maybe wikipedia is the way to go? I did contribute myself a little
there.

The software raid howto is dated v. 1.1 3rd of June 2004,
http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO.html
also pretty old.

best regards

I've found some information in 

/usr/share/doc/mdadm/FAQ.gz

I'm wondering why this file is not advertised anywhere
(eg. in 'man mdadm'). Does it exist only in debian packages, or what?
With 'man 4 md' I've found a little sparse info about raid10. But
still I don't get it.

I have added a FAQ section to our howto wiki, and added a reference to
the above Debian FAQ, along to a few comments on it.

great, thanks, for reference it's here:

  http://linux-raid.osdl.org/index.php/Mdadm-faq

I'm wondering, that maybe we could copy/paste that FAQ into that
page? After all that website is the ultimate source of information
about linux-raid. Whatever is updated in that FAQ would hopefully
find its way back into the original FAQ...?

That was my plan at first, but then I discovered (from reading the first
couple of lines...) that there already was a web page for it.

I hesitate copying the page as it is already maintained.
But my idea was also the harvest the best info out of the outdated FAQs
and then maintain it on our wiki.

I have written to faqs.org but got no reply. I'll try again...

Until people link to and use the new wiki, Google won't find it.

great idea! I belive that wikis are the best way to go.

Everyone that has a website - link to that wiki RIGHT NOW! And we
will have a central place for all linux-raid documentation. Findable
with google.

There should be a link to it from vger.kernel.org. Or even the
kernel.org itself. Mailing list admins - can you do it?

best regards.

What is this site? The link does not provide a faq on linux raid.
Why is it linked, then?

And the link provides dubious ads on having won something.
Is this site for real?

Should we have it removed from our list description?

It used to be the LDP site - it got hijacked.

IMO The wiki is the most relevant link to put there now.

It is a real 'exploit old hyperlinks' commercial bottom feeding site, yes.

Yes!
