perfSONAR User Q&A and Other Discussion

[Jessica repka <>]

Jean-michel,
So I ran into this issue while on vacation with one of the updates.
If you disable the updates you can decide when to update them. This can be found here, http://docs.perfsonar.net/manage_update.html#manage-update-auto-disable .
I'd also just do a yum roll back disable them do your yum update for the OS, then make a decision on when to update and install.

Thank you,
Jessica Repka

Hello all,

Recently, some packages where automatically updated on our Perfsonar
boxes while I was sure of having disabled yum autoupdates.

Digging a bit, I found that when updating (manually) the package
perfsonar-toolkit-systemenv-testpoint, a post-install script named
"/usr/lib/perfsonar/scripts/system_environment/testpoint/enable_auto_updates"
is run and it reconfigured my systems to perform yum autoupdates. An
extract of the script is clear on the subject :

[...]
# Make sure download_updates and apply_updates are on in centos 7
if [ -f "/etc/yum/yum-cron.conf" ]; then
     sed -i "s/download_updates = .*/download_updates = yes/g"
/etc/yum/yum-cron.
conf
     sed -i "s/apply_updates = .*/apply_updates = yes/g"
/etc/yum/yum-cron.conf
fi
[...]

=> I think this knob should be left for the system administrator to
    decide.

I found one of my Perfsonar boxes hanging following auto-updates,
I think it is better to decide when to apply them and be here to check
that the boxes are still functional after, reboot if necessary.

JM
