[Rodolph]

Hello ,

I don't see the vg00 in the /etc/lvmtab.
Someone have an idea ?
thanks a lot

Send the output of /etc/lvmtab !

Here the message ...

root@serv1:/etc# vgdisplay -v vg00

Information in "/etc/lvmtab" differs from that in "/etc/lvmpvg".
VG "/dev/vg00" is not defined in file "/etc/lvmtab".
vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vg00".
root@SUP011:/etc#

You can use vgscan to rebuild the lvmtab file. First rename /etc/lvmtab to something else, then do a; vgscan -avp

This will preview what its going to do - you should see it list its going to add in vg00. If it does then run again without the p option and it will recreate /etc/lvmtab and you should be fixed.

Hi
Try this.
mv /etc/lvmtab /etc/lvmtab.old
#vgscan.
make sure your database is down and no user is on the system.

[Rodolph]

I have already done the vgscan.
nothing have changed...

[Animesh Chakraborty]

Did you move the lvmtab first ?

[Rodolph]

yes, I did.

Hi,

You need to check the /etc/lvmpvg file to see if it reflects the correct situation.
This file is ASCII and editable.

[Bill McNAMARA_1]

are you viewing your lvmtab as follows:

strings /etc/lvmtab

ll /etc/lvmconf/

and

ll /dev/vg00

Later,
Bill

[Ravi_8]

Hi,

#mv /etc/lvmtab /etc/lvmtab.old
#vgscan

This must work, and you should be able to see vg00 in lvmtab file

Hi Rodolph,

What is /dev/vg00/perf? Is it something recent, how was it created?

regards,

Darren.
