quick question about this, been looking for a good solution for this a long time. Any filesystems that can loose connectivity? I have a setup where I can't guarantee all the computers will stay stable, but it's only a setup for temporary storage anyway (1gb networks, temporary storage is for rendering files).
> 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
> to use)
> 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.
