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.

Description Jan Hutař 2014-09-02 12:47:59 UTC 
Description of problem:
`foreman-rake bootdisk:generate:host NAME=foobarbaz.katellolabs.org` fails with "undefined method 'empty?' for NilClass::Jail (NilClass)"


Version-Release number of selected component (if applicable):
Satellite-6.0.4-RHEL-6-20140829.0


How reproducible:
1 of 1 attempt


Steps to Reproduce:
1. Sync RHEL6 and RHEL6 RH Common Red Hat repos
2. Create content view and publish it to the Library
3. Create new host with some random values
4. # foreman-rake bootdisk:generate:host NAME=foobarbaz.katellolabs.org --trace


Actual results:
# foreman-rake bootdisk:generate:host NAME=foobarbaz.katellolabs.org --trace
** Invoke bootdisk:generate:host (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute bootdisk:generate:host
rake aborted!

Comment 1 RHEL Program Management 2014-09-02 13:02:57 UTC 
Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.
Comment 3 Lukas Zapletal 2014-09-02 13:32:39 UTC 
Jan, this is known behavior. You need to turn off safemode_render value (to false) in main Settings.

[root@dell-pe2950-01 tmp]# foreman-rake bootdisk:generate:host NAME=fsdfsdf.katellolabs.org OUTPUT=/tmp/test.iso
Size of boot image is 4 sectors -> No emulation
Total translation table size: 2048
Total rockridge attributes bytes: 0
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 0
339 extents written (0 MB)
Wrote /tmp/test.iso

We should report it maybe better. I'd go for doco only maybe if you like.

Comment 4 RHEL Program Management 2014-09-02 13:35:49 UTC 
Development Management has reviewed and declined this request.
You may appeal this decision by reopening this request.
Comment 5 Lukas Zapletal 2014-09-02 13:39:01 UTC 
Ok I am taking it back, this does work even when safemode is turned on.

But I am unable to reproduce, see above. Works for me.

Have you edited the template?
Comment 6 Dominic Cleal 2014-09-02 13:41:18 UTC 
Looking at the error, I'd suggest it's hitting one of these three tests and failing:

app/views/foreman_bootdisk/host.erb
8:bootdisk_raise(N_('Host has no IP address defined')) if @host.ip.empty?
11:bootdisk_raise(N_('Subnet (%s) has no gateway defined'), @host.subnet) if @host.subnet.gateway.empty?
12:bootdisk_raise(N_('Subnet (%s) has no primary DNS server defined'), @host.subnet) if @host.subnet.dns_primary.empty?

So the issue is that either the IP, subnet's gateway or DNS primary server isn't specified.

That a safemode error is given is a bug, somewhere.
Comment 7 Dominic Cleal 2014-09-03 11:57:01 UTC 
To reproduce, note that either:

a) the host must have no IP address given
b) the subnet must have no gateway or primary DNS

What's more, they must be nil rather than empty strings - probably creating them through the API or CLI, rather than the UI will do this.
Comment 8 Jan Hutař 2014-09-03 19:17:23 UTC 
Yes, that makes sense. But I'm pretty sure I have used webUI to create the host and I have set minimum things I could to make it create new host (e.g. I'm pretty sure I have not fully filled subnet).

Comment 13 Johan Swensson 2015-06-23 11:42:00 UTC 
I ran in to this when the subnet did not have any DNS servers provided. The error went away after adding at least a primary DNS on the subnet.
Comment 14 Bryan Kearney 2015-08-11 13:24:33 UTC 
This bug is slated to be released with Satellite 6.1.
