#vgdisplay -v vg00

I would like to delete vg02.

bash-3.2# vgremove vg02
vgremove: Volume group "/dev/vg02" does not exist in the "/etc/lvmtab" file.
vgremove: Couldn't remove volume group "vg02".

bash-3.2# strings /etc/lvmtab | grep -i vg02
bash-3.2# strings /etc/lvmtab | grep -i vg00
/dev/vg00

can someone please help me removing PVG Name vg02 from the system?

Thanks

Hi Shankar,

Try

# vgexport /dev/vg02

Hi,

vgdisplay -v vg00 should not show anything about vg02. Especially this details..

>>>>>
PVG Name vg02
PV Name /dev/dsk/c3t0d0
>>>>>>

Are you sure vg02 exist on the system. confirm with

#vgdisplay -v vg02

You could use this command to entirely remove vg02 from the system

#vgexport -v vg02

Hi Robert,

Thanks for quick response,

I did what you suggested, and here is output.

bash-3.2# vgexport /dev/vg02
vgexport: Volume group "/dev/vg02" does not exist in the "/etc/lvmtab" file.
vgexport: Couldn't export volume group "/dev/vg02".


Thanks

Hi,

vg02 does not seem to be exist.

bash-3.2# vgexport /dev/vg02
vgexport: Volume group "/dev/vg02" does not exist in the "/etc/lvmtab" file.
vgexport: Couldn't export volume group "/dev/vg02".

bash-3.2# vgdisplay -v vg02
vgdisplay: Volume group "/dev/vg02" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vg02".

bash-3.2# ls -ld /dev/vg*

I need glasses :)

--- Physical volume groups ---
PVG Name vg02
PV Name /dev/dsk/c3t0d0

You have physical volume group named vg02!

# strings /etc/lvmpvg

Hi,

It is sure that, vg02 is not exist on the system.

I think somebody might have wrongly updated the file /etc/lvmpvg file. That is why you are getting this message

--- Physical volume groups ---
PVG Name vg02
PV Name /dev/dsk/c3t0d0

You can rename this file to get rid out this message from vgdisplay.

#mv /etc/lvmpvg /etc/lvmpvg.old

That fixed the problem!!!

Thank you all for your support :)

vgexport is the command


simply vgexport volume group name
