defect: "Attribute(description) does not pass the type constraint"

[Eric Hammond]

As pointed out here:

  http://groups.google.com/group/ec2ubuntu/browse_thread/thread/7dfcc9e7264882eb

This error message happens regularly now:

ec2-consistent-snapshot: ERROR: create_snapshot: Attribute
(description) does not pass the type constraint because: Validation
failed for 'Maybe[Str]' failed with value HASH(0x1f89d28) at (eval
219) line 68

In the above thread, John Shields points out a potential workaround.

This has been resolved in version 0.1-8 now available on the Alestic PPA.

This problem seems to still exist:

 ec2-consistent-snapshot --aws-access-key-id xxxxxxxxxxxxxxxxxx --aws-secret-access-key xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx --description "DB server $(date +'%Y-%m-%d %H:%M:%S')" --xfs-filesystem /db --mysql --mysql-host localhost --mysql-username root --mysql-password xxxxxx vol-xxxxxx vol-xxxxxx vol-xxxxxx vol-xxxxxx

It does take a snapshot of the first volume, but only the first volume.

Installed versions:

Net::Amazon::EC2 is up to date (0.12).

This looks like a completely different bug since the error is "Attribute (progress) does not[...]" instead of "Attribute (description) does not[...]".

You may submit a new bug report, but my suspicion is that it is an issue in side of Net::Amazon::EC2 and not in ec2-consistent-snapshot.

In the Net/Amazon/EC2/Snapshot.pm on your system, try changing this line:

  has 'progress' => ( is => 'ro', isa => 'Str', required => 1 );

to this line:

  has 'progress' => ( is => 'ro', isa => 'Maybe[Str]', required => 0 );

Nicholas: Just chatted with Jeff Kim. He'll be pushing out a new version of Net::Amazon::EC2 to fix the "Attribute (progress)" problem you are seeing. Thanks for bringing this up. (Again, it's separate from bug 485692 here, so this is remaining "fix released").

[Nicholas Sherlock (n-sherlock)]

Whoops, didn't notice that difference :). Thanks for the update.

[Jeff Kim (jkim)]

Just as an update to this I released Net::Amazon::EC2 version 0.13 yesterday with the fix to the progress attribute bug in place.
