[linux-lvm] one PV crashed

[Turbo Fredriksson]

I have (had) 6 PV's in my VG. The last one crashed (the whole disk
seems to have broken totaly).

It don't seem possible to restore the information (not without spending
$$$ to a data recovery company), so how do I get the data stored on the
OTHER disks?
