Removal of Old Gems Fails

[kemra102]

Cookbook version

4.0.4

Chef-client version

12.17.44

Platform Details

CentOS 7.2.1511 (Core)

Scenario:

Using any resource from this cookbook fails as the new Gems conflict with the old ones.

Steps to Reproduce:

1. Use a pre-4.x version of the cookbook to create some lvm resources.
2. Update to a 4.x release of the cookbook.

Expected Result:

Old Gems should be removed, new Gems should be installed & Chef run continues without any changes to the system otherwise.

Actual Result:

Chef run fails. It claims the old Gems are removed but cannot install the new ones as the binaries conflict with the old ones:

* lvm_physical_volume[/dev/sdb] action create
    * chef_gem[/dev/sdb_di-ruby-lvm-attrib_removal] action remove (up to date)
    * chef_gem[/dev/sdb_di-ruby-lvm_removal] action remove (up to date)
    * chef_gem[chef-ruby-lvm-attrib] action install

If you can please test the changes to the cookbook in an environment with a private rubygems source that is not rubygems.org and without access to ruby gems.org. So far I'm running into long waits and timeouts.

@MarkGibbons I can't as we don't have one right now.

A colleague of mine removed the old gems manually and ran Chef again and it worked OK.

It seems there is an issue running uninstall on the old gem as shown here:

1 [root@pgsql001]:[~] ~>  /opt/chef/embedded/bin/gem uninstall di-ruby-lvm-attrib
Remove executables:
	generate_field_data

in addition to the gem? [Yn]  Y
Removing generate_field_data
Successfully uninstalled di-ruby-lvm-attrib-0.0.27

I guess Chef can't hit y so it fails this part?

thanks @tas50 whats the release date on this?

[tas50]

Just pushed it up

[sanguis]

sweet as thanks!
