XFS on LVM2, 1st drive lost

[vtech@xxxxxxxx]

Hi,

I have LVM2 logical volume built of 6 harddrives (total capacity 1.3TB).
There is a single XFS filesystem on top of it.
The 1st drive (ie. pv0) died, so I'm missing the XFS filesystem headers.
What are my chances to rescue the data from drives, which are OK? (Over
80% of data). What should I do/try?

Thank You, Vit Kavan

PS.: Yes, I know, it's a stupid design. I'll never do it again, I promise
:)
