According to our documentation the "key" value has the
following
meaning: "Providing an identifier for the volume which is globally
unique. This cannot be set when creating a volume: it is always
generated." The currently used keys for gluster volumes consist of the
gluster volume name and file path. This can't be considered unique as a
different storage server can serve a volume with the same name.
Use the full URI as the key for the volume to avoid ambiguity problems.
The full URI cannot be considered unique, either, as both
gluster://hosta/volume/file and gluster://hostb/volume/file may resolve
to the same file. I think we are better off documenting that a key is
unique for some pools, but best effort for others, and not change what
we have already been outputting. But if we DO keep this patch, you also
need to change the documentation that gives examples of gluster keys.
