[linux-lvm] success report 2.4.10 + 1.0.1-rc2 + diff

[Conny Brunnkvist / dimac.net]

I tried the exact same approach, except having earlier (at v1.0) run
pvversion and converted to v2 metadata as I was upgrading from 0.9.x betaY.

But it did NOT work properly for me. Compiles OK, but after a reboot vgscan
fails:
 ERROR "pv_read_pe(): PV size invalid" can't get data of volume groups "vg0"
from physical volumes.

I really can't afford to loose my vg, so I'm sort of desperate for a
solution right now. Btw, going back to my old kernel version (2.4.4) didn't
help, either. 911!

"Possibly" - what does that mean? You don't remember?! :)
