[linux-lvm] volume group and physical volume

[narsimha.kulkarni at bt.com]

I am trying to create volume group and physical volume.


when i do vgscan 

helena:/etc # vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "helena_vg"
vgscan -- ERROR "lv_read_all_lv(): number of LV" can't get data of volume
group)
vgscan -- ERROR "lv_read_all_lv(): number of LV" creating "/etc/lvmtab" and
"/e"

the conf file for helena_vg is not to be found. how can i completely remove
it.

helena:/etc # vgremove helena_vg
vgremove -- volume group "helena_vg" doesn't exist

then i want to remove this PV /dev/hda3

pvscan -- inactive PV "/dev/hda3"  is associated to an unknown VG (run
vgscan)
