You need to do "lvchange -ay ubuntu-vg/root" and then it will show
up under /dev/mapper.<br>

I would like to be able to temporarily
move a disk from one Linux system to
another. The disk has a complete LVM2
volume group on it which I would like
to mount on the second system.
However, I may or may not be able to
mark the volume group as "exported".<br>
<br>
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?<br>
<br>
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.<br>
<br>
Is there a better way?<br>

Boot a LiveCD on the to-be-scanned VM?<br>
<br>
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.).<br>
<br>
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.<br>
<br>
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.<br>
