Yes. This is possible with NBD 2.0 and later (earlier nbd tools has
limitation of 4GB per shared disk/volume/device). You need to
compile the NBD (Network Block Device) module in the kernel too.
Then simply run on the server (the machines hosting spare volumes):
nbd-server 10000 /dev/hdax (replace 10009 with the port you want
On the client machine (where you want to run LVM to collect all
nbd-client IP port /dev/nbd/0
For each server you connect simply change the IP/port and the NBD
device number. After this you run "vgscan" and "vgchange -ay vg"
You should be warned though. If you loose network connectivity you
can end up with filesystem damage.
