Tzach,

I don't think this is something we want to disclose to clients. It's a
deployment error and it should be reported in Glance's logs instead of
HTTP errors.

Title:
  Multiple store NFS none informative cli error, when same folders
  configured twice

Status in OpenStack Image Registry and Delivery Service (Glance):
  Triaged

Bug description:
  Description of problem:

  When configuring Glance for multiple store NFS backend, if "by
  mistake" two same folders are used, image upload fails as it should
  but cli error is none informative.

  glance-api.conf ->
  filesystem_store_datadirs=/mnt/nfs1/images/:1
  filesystem_store_datadirs=/mnt/nfs1/images/:1

  
   [root@dhcp160-213 ~(keystone_admin)]# glance image-create --name flotz --disk-format qcow2 --container-format bare --file c6-x86_64-20130910-1.qcow2 Request returned failure status.
  500 Internal Server Error
  Failed to upload image 75a41998-b0ce-4be1-b3c8-d1618362f4e8
      (HTTP 500)


  Version-Release number of selected component (if applicable):
  RHEL7 
  python-glanceclient-0.12.0-1.el7ost.noarch
  openstack-glance-2014.1-2.el7ost.noarch
  python-glance-2014.1-2.el7ost.noarch

  
  How reproducible:
  Every time

  Steps to Reproduce:
  1. Configure Glance to use multi store NFS back-end, give same NFS shares twice.
  2. Try to upload image

  Actual results:

  Request returned failure status.
  500 Internal Server Error
  Failed to upload image 75a41998-b0ce-4be1-b3c8-d1618362f4e8
      (HTTP 500)

  
  Expected results:

  A more detailed informative error on CLI would be helpful, maybe
  similar to api.log "Reason: Directory /mnt/nfs1/images/ specified
  multiple times in filesystem_store_datadirs option of filesystem
  configuration Disabling add method."
