Note that if looking for Linux rootkits, NFS export will/can hide them. Otherwise, yeah...

You could just mount the remote disk over the "network" and then scan it.

Is there any way to import a volume group which isn't marked as "exported"? Or to use the destination system to mark it as such?
Background: I've been tasked with creating a Linux VM (Virtual
Machine)
with ClamAV on it which can scan other Linux VM disks. To do that I
assumed
I'd shut down the target system and mount its disks on the scanning
VM, do
the scan, then remove the target disks from the scanning VM.
Is there a better way?

Boot a LiveCD on the to-be-scanned VM?
Actually, I would boot a LiveCD in the dedicated VM anyway. Sysresccd works well, and usually has a reasonably-up-to-date version of
ClamAV.
Also, it doesn't require 3D video, so it works well in a VM (unlike,
say,
Ubuntu, CentOS 7, etc.).
If you want a regular HDD (vdd?) installed linux system anyway,
simply
running "pvs", "vgs", "lvs" and then mounting the FS out of
/dev/mapper
should work. You might have to do a "{pv,vg,lv}change -ay" if it's
not
marked as active. Do NOT flag it as exported once you're done
scanning it,
or the origin system may refuse to automount it.
If you're running in VMware, I would recommend hot-adding the volume
to
the scanning VM so that it never accidentally tries to boot off it.
