[jira] [Commented] (DTACLOUD-249) unable to describe in detail a
storage volume with ec2 driver
[ https://issues.apache.org/jira/browse/DTACLOUD-249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406448#comment-13406448 ]
Marios Andreou commented on DTACLOUD-249:
-----------------------------------------
Hi Deepika - seems like you hit a ruby 1.8 vs 1.9 compatibility issue (I see from your trace you're on ruby 1.9.1 - had some issues installing that but was able to reproduce the problem with ruby 1.9.2):
[marios@name deltacloud]$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-linux]
[marios@name deltacloud]$ irb
irb(main):001:0> "String".to_a
=> ["String"]
irb(main):002:0> exit
[marios@name server]$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
[marios@name server]$ irb
1.9.2-p290 :001 > "String".to_a
NoMethodError: undefined method `to_a' for "String":String
from (irb):1
from /home/marios/.rvm/rubies/ruby-1.9.2-p290/bin/irb:16:in `<main>'
1.9.2-p290 :002 > exit
You can see from the first line of your trace that this problem is hit on the aws gem side of things:
/var/lib/gems/1.9.1/gems/aws-2.5.6/lib/ec2/ec2.rb:1190:in `describe_volumes'
I just pushed a fix on our (deltacloud) side that will guard against this. If you are able to get the latest code (e.g. git clone git://git.apache.org/deltacloud.git - see http://deltacloud.apache.org/getting-sources.html ) you'll see the fix (i.e. the problem should disappear) - otherwise, a new gem should be out soon with this fix
thanks for reporting the issue,
marios
