Creating LVM in Redhat

In this case i want to implement LVM technology.
I have 12 hadisk in my server (File Server), Redhat operating system.
1 hardisk only operating system and the others will be data storage.
That all will be implement by LVM.
Before that, which is better create LVM after installing operating system or while  installing operating system (Redhat)?
Can you tell us how to implement the best?

And if one of hardisk crash that implemented LVM, how to solve it so that File Server runs well.

Thanks advanced!

OK for the installation.

There are 12 hardisk until 9 TB.
Ex: sda - sdl
100 MB of sda I make for /boot.
All of disks except /boot I make one group.
For data I make 8 TB, ond other for /usr, /tmp, etc.

I just afraid if one of my disk crash, ex: sdb.
What should I do so that my File Server run well?
For information, I backuped with Bacula.

I ever heard about SNAPSHOT?
How about that?

Thanks!

@small-student
What do you mean about keep the rest with /?
It is same with /boot on saparate partition.

@master
If I use RAID, 1/3 of my storage will be used for mirror right?
It's mean I lost 1/3 of my storage.
That is why I used LVM.
Any suggestion master?

Thank you very much!
