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 />
