a user-raid list for non gurus?

Hi all,

even thought I'm subscribed to this list since quite a lot of time, I only
can grab a little purcentage of the discussion due to technical gap.

When it happens that I ask something to the list I normally get unanswered
even on problems that in my opinion shouldn't be considered really
specific to my setup. Here just the last 2 questions:

http://marc.theaimsgroup.com/?l=linux-raid&m=114185900020437 &w=2
http://marc.theaimsgroup.com/?l=linux-raid&m=114120476328121 &w=2

I'd like to know if there is a users-linux-raid where these kind of
questions get answered, if I should just insist on this list, or if I
missed some document (possibly a complete howto) that already gives
thorought info on how to cope with troubles, or a wiki.

I feel like linux-raid is missing a good howto. The documentation you can
find is often outdated or incomplete and it only saldomly helped me to get
out of problems.

The sad part of all this is that with raid systems you are not normally in
the mood/position to test things. You would much more prefere to arrive at
the crash already with the knowledge on how to cope with it... but the
crash is never as the one you simulated failing the device...

Thanks for your attention and you job anyhow

PS: In case anybody feeels like writing a complete howto I could
help... with the index ;-) of what a system admin -not a raid guru-
would like to read to understant raid (not just to setup)

Maybe you just have to ask again. It worked this time....

No, this list is the best place to ask. Questions usually get
answered, but not always. People are busy etc. Feel free to ask a
second time if you haven't had an answer.

To have a good howto, we need someone to step forward to write it.
They don't necessarily need to know all the answers - they can ask
here - but it would help if they know some good questions, and are
reasonably good at technical writing.

thanks for the encouragement and for the nice reply.

wouldn't you think that a good wiki with a structured skeleton could help
knolwdged people give their contribution without asking too much time?
Should people feel this is any interesting I could try to find the time to
help in this (on the 'questions' side rather that on the 'ansers' one ;-)

The problem is that with a user list, the people who are best able to
answer your questions are unlikely to see them. While many people have
good intentions, in practice we lack TIME to read yet another list,
particularly those where the chance of finding something useful to an
experienced user are small.

Right now RAID is moving so fast that it would be out of date, and
that's less helpful than nothing. The mdadm man page is the howto, and
the only thing remotely able to provide information on exactly what you
have installed today.

I agree that people don't feel like messing with their RAID when they have it working! I would love to change my setup, but there is no funding for a backup system to make backing up several TB convenient, and no time to spend doing it the hard way.
