I'm having a very similar problem. When I run vgscan, I get: [root@filmore jdiehl]# vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- found active volume group "Database2" vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get data of volume group "Database2" from physical volume(s) vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" creating "/etc/lv mtab" and "/etc/lvmtab.d" Any ideas about how to recover without losing my data. I need to get going soon, so if I haven't fixed it by late this week, I'm going to reformat.... And lose several Gb of data. Thanx, Mike Diehl, Network Monitoring Tool Devl.
