Incorrect volume name or error "no Volumes were given"

[yongzhang]

Hi,

Can anyone explain why all of my volume names were "devops-registry" from metrics?

gluster_exporter version: v0.2.6
Glusterfs server version: 3.10.0

@hiscal2015 thanks for reporting this error, seems that gluster_node_size_free_bytes and gluster_node_size_total_bytes are affected.

The warning message is more or less a reminder, that you're implicitly querying all volumes.

@ofesseler Expecting v0.2.7, this is a wonderful exporter!

[yongzhang]

@ofesseler Thanks for fixing this. Can you upload the latest release to the "release" tab? Seems I have some issues to build... Thanks.

[ofesseler]

I made a new release
