vgdisplay and lvmtab

[Teck Sim]

When I did a bdf:
I see all my /dev/vg00 and /dev/vg01

but when I did a vgdisplay, it only display vg01, but not vg00?

Please help.
Thanks

Hi Teck,

When you do a vgdisplay w/no parameters it will show all VGs.
I suspect the vg00 info has scrolled on up & off the screen.
Do
#vgdisplay -v | more
This will give greater detail & hold it to a screen at a time.

HTH,
Jeff

I agree with Jeff.

Another method would be to do:

# vgdisplay -v > /tmp/vgdisplay.txt

# view /tmp/vgdisplay.txt

Hello,

Instead try vgdisplay -v vg00 to get info on vg00.

vgdisplay by default will disaply information for all the VG's. If you want to see perticualr vginfo then try above method.

This is what I did:

[wally:/etc] # vgdisplay -v vg00
vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vg00".

Even with vgdisplay without any parameter, it shows only vg01, not vg00.

With bdf, this is what I get:

Hi Teck,

Sounds like the /etc/lvmtab file is corrupt or bad - do this
#mv /etc/lvmtab /etc/lvmtab.bad
#vgscan -v

This will create a new lvmtab file with the correct inof. NOTE - You must remove or rename the existing lvmtab file or vgscan will use it for reference.

HTH,
Jeff

Hi Teck:

Based on your posts the last week, I surmise that you have been updating or otherwise cold-installing your server. What was the last thing you did before you got this error?

Regards!

Also note that you can do what Jeff suggests while the machine is up and nothing should be impacted.

I can't exactly remember what I did the last time, but now the problem is solved. Thanks to all of you.
