OK, so I've doing some more testing on this - since I couldn't remember
preciseley the time I submitted the previous jobs so I've recorded times
more accurately now.
Yesterday morning between 1045-1100 GMT I submitted a number of jobs to run
at 9AM over the next 4 days too see when they were picked up and executed.
The first job was scheduled to execute today after 9AM, according to the
schedule its showing:
- *Summary:*
Package Install scheduled by mattb
- *Details:*
This action will be executed after 12/23/14 9:00:00 AM GMT
This action's status is: Queued.
This action has not yet been picked up.
Packages Scheduled:
- kernel-2.6.32-504.3.3.el6.x86_64
- rsyslog-5.8.10-10.el6_6.x86_64
- kernel-firmware-2.6.32-504.3.3.el6.noarch
- *Time:*
12/23/14 9:00:00 AM GMT
I'm surprised that the action "has not yet been picked up" since the server
checked in (via the spacewalk proxy) just 35 minutes before the "execute
after" time.
I've checked and times on the three involved nodes (spacewalk, proxy &
client) are all in sync.
