Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

two discovered hosts with mem/disk zero
Comment 5 Bryan Kearney 2015-05-05 13:44:08 UTC 
Created redmine issue http://projects.theforeman.org/issues/10375 from this bug
Comment 6 orabin 2015-05-05 20:14:27 UTC 
discovery_attribute_set should have been created when the hosts were discovered.
I reproduced only when trying to use hosts discovered before discovery_attribute_set was added or removing the record from the DB.
If you find steps to recreate a discovered hosts with no memory please send them to me.

There is a workaround so I don't think it should be a blocker.
You can see in the logs that the host id is 2 so refresh it's facts by:

hammer discovery refresh-facts --id 2 

and then try listing the discovered hosts again.
If this happens with more hosts refresh their facts too.
Refreshing the facts will recreate the discovery_attribute_set.

1) Discover a host
2) Host::Discovered.all.first.memory -> OK
3) Click on Provision button to get to the form (do not yet submit or anything)

Upstream bug assigned to lzap
Comment 13 Sachin Ghai 2015-05-22 13:39:08 UTC 
Verified with Sat6.1 GA snap5. 

Looks like the reported issue is no longer reproducible. Now If I close the discovered host form without updating or submitting. UI shows all facts correctly. Earlier all facts were being set to '0'.

Since this issue is no longer reproducible. Moving this verified..
Comment 14 Bryan Kearney 2015-08-11 13:36:44 UTC 
This bug is slated to be released with Satellite 6.1.
Comment 15 Bryan Kearney 2015-08-12 14:02:03 UTC
