[linux-lvm] Vgscan problem

[Patrick Boutilier <boutilpj@ednet.ns.ca>]

I am getting the following EROR -364 when running vgscan. The volume
group and logical volumes are actually in use and reiser filesystems
mounted on them.

Should I be able to run vgscan when the vg is active? If so what could
the problem be? The machine was rebooted 15 days agao with 2.2.15pre17
and vgscan worked fine then. I ran accross the problem today when I was
trying to run lvm-viewer which runs vgscan when it starts.

Thanks.
