In case 1 you just physically removed the pv2? And vgdisplay shows you
the error message of the missing pv in the vg? Or you removed the pv
from the vg, vgdisplay showing you that the vg is ok?

In case 2 you just log the iscsi target out, which is the same as just
pulling the cable off, and vgdisplay doesn't show you, that the vg is
damaged, cause the pv2 is missing?

If you want to remove the pv2 from the vg without getting it in error
state, you have to remove the pv from the vg before iscsi-logout.

Anyways, it would be quite helpfull to cut-n-past the output of
vgdisplay into your mails instead of telling us, that it's not
displaying properly ;-).

Ciao
Klaus
