hi narsimha, If u want to completely remove ur PV (i.e. if u want to lose ur data) then there is a very simple way to get rid of this problem. Just do following.... dd of=/dev/hda3 ......hda3 becuse ur PV resides on that <enter approx 50 chars> <press cntrl+d> Of course it not the recommend solution, but it will solve ur problem :-) Actually ur VGDA data on the disk may be corrupted, that's why u r getting this error message. When u create a PV/VG, some data is written on the disk (on some initial disk blocks). So if u erase that by doing 'dd', then u can create fresh PV/VG using that disk. ----- Original Message ----- From: <narsimha.kulkarni@bt.com> To: <linux-lvm@sistina.com> Sent: Tuesday, May 27, 2003 8:37 PM Subject: volume group and physical volume > 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) > > > narsimha > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
