ONE EC2 upload error

Posted on by | Leave a reply

I encountered the an error while experimenting with the OpenNebula (ONE) EC2 interface. I tried to upload an image file, to a OpenNebula host running CentOS 5.3 with ONE 1.3.8. After a couple of seconds the command exited with the following error:

[rogierm@cloudtest3 ~]$ econe-upload /home/rogierm/centos5.img
image /home/rogierm/centos5.img
/usr/local/one/lib/ruby/econe/EC2QueryClient.rb:164:in `http_post': server returned nothing (no headers, no data) (Curl::Err::GotNothingError)
from /usr/local/one/lib/ruby/econe/EC2QueryClient.rb:164:in `upload_image'
from /usr/local/one/bin/econe-upload:116

I informed the ONE developers of this issue on their mailing list and Sebastien Goasguen pointed me to the correct solution. There seems to be an error in the curl implementation on CentOS. I installed the multipart-post gem and executed the econe-upload with the (yet undocumented) switch ‘-M’. This fixed the problem.

Install gem:

[root@cloudtest3 ~]# gem install multipart-post

Run the working econe-upload command:

[rogierm@cloudtest3 ~]$ econe-upload -M /home/rogierm/centos5.img

OpenNebula EC2 error

While experimenting with OpenNebula and trying to build a public cloud with the EC2 interface to OpenNebula I encountered the following problem in the code:

[rogierm@cloudtest3 one]$ econe-upload /home/rogierm/test.img
/usr/lib/ruby/1.8/rdoc/ri/ri_options.rb:53: uninitialized constant RI::Paths (NameError)
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from /usr/lib/ruby/1.8/rdoc/usage.rb:72
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from /usr/local/one/bin/econe-upload:61

I fixed this problem by adding the following line (above the other require statements) in econe-upload, or any other command giving the same error:

require 'rdoc/ri/ri_paths'
