Hi, the namespace of the fog-vsphere has been changed, so if you have old data cached, it will fail as you are describing.
But as you are saying it is failing only randomly, it is very weird. Could you share more information with us?fog-vsphere in your Gemfile.lock?
Could you clean the cache by foreman-rake console and Rails.cache.clear, so we know it was not an old stuff hanging around?
And is it by any chance load-balanced or HA setup?

Hi,
But as you are saying it is failing only randomly, it is very weird. Could you share more information with us?
Yes, this REST query fails kind of randomly. When the query fails I have to resend the REST query (1 to 3 times) before I get a valid result. On the Foreman instance where this issue occurs are 2 VSphere server configured as compute resources (id 4 and 5). It seems like that the problem only appears on resource id 4 and only if caching is active.
I guess you are running foreman on debian based system, is that correct? If so, could you please share what version is the fog-vsphere in your Gemfile.lock ?
Nope, I’m using Foreman 1.20.2 on CentOS 7.6 and the standard fog-vsphere version (tfm-rubygem-fog-vsphere-2.3.0-2.el7.noarch).
Do you have more instances of foreman, or just one?
I’ve in total 4 Foreman instances on different servers (2x 1.19.1 and 2x 1.20.2). All standard installations. No LB or HA setup. I have this issue only on 1 instance (1.20.2)
Could you clean the cache by foreman-rake console and Rails.cache.clear , so we know it was not an old stuff hanging around?
Cleaned the caches … unfortunately no changes.
Cheers,

Sorry, there was a mistake in my first post. The sporadic error output of the REST query is actually “uninitialized constant Fog::Compute::Vsphere::Cluster ”:
$ curl --user *** -k -X GET -H "Content-Type:application/json" -H "Accept:application/json" https://foreman.***.de/api/compute_resources/4 | jq
Enter host password for user '***':
% Total % Received % Xferd Average Speed Time Time Time Current

{
"error": {
"message": "uninitialized constant Fog::Compute::Vsphere::Cluster"
}
}
I hope this makes more sense now … The rest of my observations remain unchanged.

It actually doesn’t
I really have no idea what could be the cause here, so I can try to guide you through some debugging process, to try figure it out.
You could try to add these at the begging of the method, in which it all goes down.
# app/models/compute_resources
#....
def available_clusters
require 'fog/vsphere/version'
Rails.logger.info "current vsphere version is: #{Fog::Vsphere::VERSION}"
Rails.logger.info "Fog::Compute is #{defined? Fog::Compute}"
Rails.logger.info "Fog::Compute::Vsphere::Cluster is #{defined? Fog::Compute::Vsphere::Cluster}"
#...
end
What should give us in the logs answers for:
Your code is not reloading fog-vsphere on the fly for another version
Fog is not unloaded in between the requests
If everything is all right, I guess we will have to examine the cache for it’s raw value.

Hi,
I’ve added your debug code to the available_clusters method (/usr/share/foreman/app/models/compute_resources/foreman/model/vmware.rb)

Yesterday I’ve updated another Foreman server to 1.20.2 which is now showing the same issue (sporadic HTTP 500 / “uninitialized constant Fog::Compute::Vsphere::Cluster”. This Foreman Server uses the same VSphere Server to create hosts as the other one.
Can you please try to do a “Refresh Cache” on the “Infrastructure -> Compute Resources -> Your Vmware Provider” page?
Does it work afterwards? If this is the case, does it fail again?

In my experience it works after refreshing the cache, but it does start to fail again after a short while. The only workaround I have right now is to disable the compute resource cache completely, which results in very slow host edit pages.
I’m having similar problems on 1.21.3, but I believe it happened for me on 1.20 as well.
Typically it happens when trying to edit a host in the GUI. Now and then we get the error message:
Oops, we're sorry but something went wrong uninitialized constant Fog::Compute::Vsphere::Network Did you mean? Fog::Network
We then just try again and then it works at the second or third attempt. I just did a ‘refresh cache’ on my vmware compute resource, but that didn’t help.
We’re on RHEL7 with standard rpm installation, standalone installation (no HA, no LB)
I believe it is something about rails autoloading vs passanger and fog nasty namespaces. I wonder though how comes we are hitting those now out of the blue
YES, that commit seems to have fixed the issue in my environment.

Hi,
I’m still getting sporadic HTTP 500 errors after applying the patch (same REST query, same error frequency). However the error message is now a different one:
ActionView::Template::Error: undefined method `resource_pools’ for nil:NilClass
production.log snippet:
production_log_snippet.log (20.5 KB)
Greetings,
I also get another, similar error messages in production.log, but not as frequent. I got these before the patch as well, but I don’t know exactly in what situation since it to my knowledge hasnt affected any users.
Error messages like:
2019-05-28T05:50:23 [W|app|b2706f9c] Action failed
| NameError: uninitialized constant Fog::Compute::Vsphere::StoragePod
| Did you mean? Fog::Storage
Could you guys please try to add
# app/models/concerns/fog_extensions.rb:54
require 'fog/vsphere/compute'
and try again?
I already have that line on 1.21
mzima
May 28, 2019, 10:02am
#19
the line is already included (1.20.2):
54 if Foreman::Model::Vmware.available?
55 require 'fog/vsphere'
56 require 'fog/vsphere/models/compute/cluster'
57 require 'fog/vsphere/models/compute/network'
58 require 'fog/vsphere/compute'
59 require 'fog/vsphere/models/compute/server'
60 Fog::Compute::Vsphere::Server.send(:include, FogExtensions::Vsphere::Server)
61
62 require 'fog/vsphere/models/compute/folder'
63 Fog::Compute::Vsphere::Folder.send(:include, FogExtensions::Vsphere::Folder)
64 end
Attempted the same workaround on RedHat Satellite 6.5.3 (based on Foreman 1.2.0) and am still getting the same exact errors as mzima.
It seems this issue appears in various (API, hammer, and webUI) in areas which interact with compute profiles or VMware compute resources in general. As mzima has said, applying the workaround from https://github.com/theforeman/foreman/pull/6803/files seems to change the error to this “ActionView::Template::Error: undefined method `resource_pools’ for nil:NilClass”, but the intermittent issue still persists.
After implementing the workaround to app/models/concerns/fog_extensions.rb:54, and disabling compute resource caching, it seems the issue is resolved, but both were required.
I hope I’ve found solution for this issue: https://github.com/fog/fog-vsphere/pull/267

I gave myself decent time to think about it, and nothing came up.
