vgdisplay: Couldn't read the internal id of volume group

[Shane Reber]

I am trying to create a volume group with a logical volume and a filesystem. I created them fine, and everything looks ok, but I get this mssg on a vgdisplay of that volume group - "vgdisplay: Couldn't read the internal id of volume group "/dev/vgthis/" from
"/etc/lvmtab". vgdisplay: Cannot display volume group "/dev/vgthis"

What does that mean? How do I fix it?

Thanks!!

...guess it could be a corrupted /etc/lvmtab file...you can rebuild that by doing the following...

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

...the retry your vgdisplay command...

Try rebuilding lvmtab file ..

# cd /etc
# mv lvmtab lvmtab.save
# vgscan -v

Not to hold you responsible or anything, but is the vgscan -av command normally ok to do while users are working on the system?

Yes
