Description Mike McCune 2016-11-11 22:47:04 UTC
+++ This bug was initially created as a clone of Bug #1369234 +++

If I attempt to delete a content view version, either from the CLI or GUI, it takes a long time to start, and typically times out in the CLI, and leads to the delete confirmation screen in the GUI to sit with an hourglass forever.

When this happens, the dynflow task shows as planning/pending, and there is a single 'ruby' process running, using 100% of one CPU core. If this is left, it eventually stops doing this, and the task starts and does eventually complete.

There was a suggestion that there was a problem with lack of entropy on the system - I installed and run haveged, and while initially it seemed like it could have helped, it seems that patience was what really helped - it just takes a *long* time to delete a content view version.

Moving all bugs POST fixed in katello 3.0.x or 3.1 to ON_QA for satellite 6.3.

cu update on case : 01683120

Just an update - I've been watching this more closely and found out that progress doesn't show during the "planning" phase. This phase usually takes the longest time. Once it goes to actual removal, then progress bar is displayed correctly in GUI.

is this supposed to be reproducible even on empty, non-promoted content-views?

i was unable to reproduce this on

# rpm -qa satellite
satellite-6.2.4-1.0.el7sat.noarch
# rpm -qa katello
katello-3.0.0-14.el7sat.noarch

`
# hammer content-view publish --id 3
# hammer content-view version list --content-view-id 3

Could not delete the content view:

Could you provide more specific steps to reproducte the issue if mine are not correct?

Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/15531 has been resolved.

Comment 3 Walden Raines 2017-08-03 18:55:57 UTC
For the CVV I removed (consisting of RHEL 7 server promoted to one environment) this took 17.56s which is a huge improvement over 10 minutes.  I am marking this as verified against sat 6.3.0 snap 9.

Neglected to mention that this is around the same time this operation takes in 6.2.z.
