Phantom Volume Groups

Rafael Casero — Thu, 22 Jun 2006 13:00:49 GMT

I'm trying to remove Volume groups no longer exist.

I have tried the following commands but nothing seem to work.

vgexport vg01
vgreduce -f /dev/vg01
vgremove /dev/vg01
lvremove -f /dev/vg01/dg01

All this cammends give the same error

does not exist in the "/etc/lvmtab" file.

HELP...

These systems are a mess, I just got thrown in at it...

Rafael,

A couple of ideas/suggestions:

suggestion one
move /etc/lvmtab to /etc/lvmtab.old
vgscan -va
vgexport

suggestion two
cd /dev
rm -rf /dev/vg01
move /etc/lvmtab to /etc/lvmtab.old
vgscan -va

All that should be needed is "vgexport /dev/vg01"; that will remove any lvmtab entries and the /dev/vg01 directory and any device nodes below it. If /dev/vg01 does not exist in lvmtab then you will see the error message but that's not a problem. Do a "strings /etc/lvmtab" and that will show you what VG's are defined.

Hi:

Well, what is it that you see that makes you believe that you need to do something?

If you have files in '/dev/vg01' but nothing recorded in '/etc/lvmtab' then it is possible that the volume group was previously 'vgremove'd. If that's the case, the device files ('dev/vg01') can be removed.

Regards!
