Hi Heinz,
Thanks for your message. To answer your questions...
The root filesystem has over 50 GB available. I ran vgscan but that did not improve the situation. What we were able to do to get vgdisplay to not output an error was...
1) modify the /etc/lvmtab file to include the filesystem which LVM claims is inactive and exported (even though it is in mounted and in use)
2) cp /etc/lvmconf/${vg}.conf /etc/lvmtab.d/${vg}
3) after steps 1 and 2, vgdisplay shows information regarding both volume groups defined; however, pvscan still shows one volume group as inactive and exported; we determined this must be due to a flag on the disks themselves, because /proc/lvm kernel info seems to show both volume groups as active
Any other info on why volume group status is not kept accurate by LVM is appreciated!! Is this perhaps a bug with LVM v 1.08
Thanks!
Dave

E.g. because your root fs is full.
FYI: all lvm commands changing the configuration write the lvmtab.
Have you tried running vgscan yet ?

I'm also hesitant to add new disks, vg's, lv's, and file systems until I can run vgdisplay without an error. Should I be concerned re: this message???
