Re: [Linux-cluster] how can I share a logical volume?



No, I can't see the logical volumes on the other nodes. vgscan doesn't show any, nor I can find any new devices in /dev.
As I couldn't find docs/examples on this particular point, I really don't know what to expect.
I'm trying with different types of logical volumes (stripped, mirrored), but didn't make a difference.
For the moment, I'm running all the stuff on virtual machines, could this be an issue?
For the moment I'm using a minimal cluster.conf, in which I just declare the nodes. Should I add specific configurations to it?

Lots of thanks.

As far as I know, you should be able to at least SEE the logical
volume as long as there is a path to the physical volumes on the other
nodes.  Are you able to see the same block devices (eg /dev/sd?) on
the other nodes?
