I want to delete non active volume group

[cbozlagan]

vgremove doesn't work if vg is not active.

That vg has lv inside

Thanks

[Redhat]

simply run vgexport

Actually the VG must be inactive for vgremove to work.

The real reason vgremove isn't working is because the VG still has an LV in it. What you must do if you want to go that route is:

# vgchange -a y /dev/vg??
# lvremove /dev/vg??/lvol?
# vgchange -a n /dev/vg??
# vgremove /dev/vg??

But, if you want the real easy way, and are absolutely sure nothing is in use, then use vgexport as said above.

# vgexport /dev/vg??
will get rid of everything, including all /dev/vg??/* files.

I executed vgscan -pv but it gave me some
'Unable to match' warning.
You can see messages below.
How can I correct these problems?

Thanks

So why are you running vgscan? What exactly are you trying to do?

[Redhat]

Pls send the "output" file after executing the following command

script /tmp/output
strings /etc/lvmtab
vgdisplay -v
ioscan -fnC disk
then press cntl+d

Hi Manojit Das,

I attached output file

[cbozlagan]

Hi patrick,

SAP NetWeaver installation document asks me to execute vgscan command.

Thanks.

It seems that you have already exported four different volume groups.

vgexport command removes the vg info from the /etc/lvmtab file, deletes the associated device files including the vg_name directory but keeps that info untouched on the physical volume (on the disk)

So if you want you can recreate (undelete) the same vgs using vgimport or clean the vg info from the disk using pvcreate -f commandon each disk.

If you are sure you do not need the data on the unmatched disks and plan to use them in a new volume group just take the second option.

hth.
