The actual data is in a few reiserfs3 partitions of unknown sizes (unknown number of LVs, approximately 4). I removed my /dev/hdb PV using vgreduce, after attempting a pvmove (but it seemed that it wasn't used). After a reboot I couldn't mount my root LV (it was a very bad idea to make a root lv), and after booting using a bootCD vgscan exited with 'error pv_read_pe can't get data of volume group from physical volume' (roughly). So this is when I tried 'pvcreate -ff' and created a new vg. However, I cannot guess at the LV information. Any help would be greatly appreciated. Thanks, -Mike
