I can access data on previous PVs (yet), but don't know how to remove PVs, there is nothing linke 'pvremove'. I can assure you there is no data (perhaps except signature) on those disks.

yes, helped quite enough, just the /dev/sd[ghi] devices are still in list of valid PVs and when I run pvscan my partitions get destroyed (I suppose because of rewriting LVM marker to the device). How do I really, physically remove the devices from the PV list?

Thanks in advance,
