loopback storage provider not completing successfully

[Charles Butler]

I am in correspondance with a CPP developer, and they are having problems using the loopback storage provider with Juju. The following excerpt is from their correspondence:

1. How to create block device on node? I've read https://jujucharms.com/docs/stable/storage topic, but I can't create devices on new node.
   metadata.yaml
   ...
   storage:
     data:
       type: block
       multiple:
         range: 2

   juju deploy --repository=. local:trusty/nedge-node

    but in log file:
    machine-1[4789]: 2015-09-18 14:38:21 ERROR juju.worker runner.go:223 exited "storageprovisioner-machine": processing pending volume attachments: creating volume attachments: attaching volumes from source "loop": attaching volume 1/0: attaching loop device: /var/lib/juju/storage/loop/volume-1-0: No such file or directory: exit status 1

@lazypower, what version of Juju is in use? Assuming 1.24, there are some bugs that may not have been fixed. 1.25 is in a much better state.

[Charles Butler (lazypower)]

Thanks for the follow up Andrew

The Juju version is 1.24.5-trusty-amd64

[Andrew Wilkins (axwalk)]

@lazypower: if it's possible, please recommend that they use 1.25 (beta1) when it's available. If not, we can look at back-porting fixes. Storage is only really stable as of 1.25; there were many bugs that required drastic changes.

[Cheryl Jennings (cherylj)]

Marking as incomplete unless the problem can be reproduced on 1.25 or higher, based on Andrew's comments above.
