LVM rezise, data lost

[UnoSD]

Hi all, i'm desperate,

I wanted to install Fedora 12, (now on my machine there is Fedora 11 64) i wanted to resize the system partition (1TB LVM in EXT4) leaving 100GB for the new system...

I started the system with Fedora 11 x86 Live, started the "Logical Volume Managment" from System->Administration and gone on vg0->Logical View->lv0 and i've done "edit properties" and resized the partition to 900GB, clicked on ok...

When i restarted the system, GRUB started, i've choose Fedora and nothing... Black screen with just the cursor, loading nothing and letting me just write...

(LVM didn't recognized my partition type before and after the resize, instead of sayng Filesystem EXT4 it said Filesystem "None"

I'm terrified also of mounting partition, there were all my important data

Please help me, Thank you

Solved! I've just setted up the partition back to the old size and it worked... It is because the LVM doesn't affects directly the partition...

Good for you.
Now is a good time to think about some regular backup

now it's time for "RAID 1"!!!!!!!!

A raid is not a backup.
Just imagine, you/someone else/a script accidentally deletes something.
A raid won't help you in this case.

Ideally, depending on the value of your data, you would have both raid and a backup.
