Couldn't remove volume group

[sfgroups]

Hi all,

I have removed all logical volume form this volume group, now I want to remove volume group vg06, but I am getting this message.

$vgremove /dev/vg06
vgremove: Volume group "/dev/vg06" still contains more than one physical volume path.
vgremove: Couldn't remove volume group "/dev/vg06".

Here is vgdisplay ouptut:

vgdisplay -v vg06

How will I remove this volume group?

Thanks

You have a couple of options:

1) Do a vgreduce on ALL physical volumes in the VG.

# vgreduce /dev/dsk/c16t1d6 /dev/dsk/c16t1d3, etc.

when that is done:

# vgremove vg06

2) Deactivate and export the VG.

# vgchange -a n vg06
# vgexport vg06

The 2nd option is definitely faster and easier.

[Robert-Jan Goossens]

take the easier route

# vgchange -a n vg06
# vgexport vg06

You have to remove the disks from the volume group with vgreduce.

Once the disks are removed, then you can remove the volume group.

Hi,

Remove all the physical volumes from VG by using vgreduce command. Then you should be able to remove the volume group.

Best of luck

Hi,

Do a vgexport instead of vgremove.Vgexport removes all information about the vg from system with single command.

#vgchange -a n /dev/vg0x
#vgexport /dev/vg0x


cheers!!

Hi,

vgexport is the best method to remove all traces of a VG frm the system

#vgexport VGname

Hi,

Nothing to add except a little advise, when you make you vgchange and vgexport use -f option with a filename. So after you can directly make the pvcreate -f on the disks which are in it and that will avoid a lot of questions the next time you'll have to use them; "Is it still used ?"

Hope this helps

Hi,

The message is self explainary, as it says it can not remove VG as it is extended to more than one physical volume.

For vgremove to work the VG should be limited to only one physical volume and this does not allow even multiple paths to same disk.

A better option will be to use vgexport which will do the same job for you and will avaoid additional steps of vgreduce from any six disks which are there.

HTH,
Devender
