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.

Scenario [Checks before upgrading to Satellite 6.3.z] failed.
The following steps ended up in failing state:
[disk-performance]
Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="disk-performance"
[root@satellite1 ~]#
This is on the same server, within about three minutes of each other. The server is a VMWare guest on a Dell Compellent SAN, probably on the front line SSDs, but I can't be certain.
Version-Release number of selected component (if applicable):
RHEL7 fully patched as of 2018-10-18
Satellite 6.3.4, but with
rubygem-foreman_maintain-0.2.11-1.el7sat.noarch
and a downgrade back to
rubygem-foreman_maintain-0.1.6-1.el7sat.noarch
to double-check what was going on
How reproducible:
Every time foreman-maintain is run
Steps to Reproduce:
1. Upgrade from rubygem-foreman_maintain-0.1.6-1.el7sat.noarch to rubygem-foreman_maintain-0.2.11-1.el7sat.noarch
2. Run "foreman-maintain upgrade check --target-version 6.3.z"
3. Observe "Disk speed" check
Actual results:
Wildly varying differences (order of magnitude) in measured/reported disk speed
Expected results:
Both versions of foreman-maintain to give vaguely similar results
Additional info:
I've tried running the newer version of foreman-maintain at various times throughout the day in case the SAN that backends this VM was busier at some times than others. There wasn't a variation of more than 2-3MB/sec for any run.
