====== Change in Yum Update Location ======
Email from Jon ->
"just created a redhat directory on astrobackup2, and modified
/etc/auto.home on astronomy to point the automount (/home/redhat) to it,
the did a
cd /var/yp
make
to push this to NIS for all other machines."
====== Update Schedule ======
Zach will start updating machines on a monthly basis on the last day of the month. After kernel updates, reboots will be required in order for new kernel to take effect (best schedule for reboots?).
== Last Time 'Yum Update' Was Run on the Machine?
**Best practice** - Run 'yum update' on one machine first to get an idea of what's being installed/updated. Then once that completes, you can run the doit scripts for CentOS 6 and 7 machines. For example:
[user@astronomy]$ /home/local/etc/doit-centos7 yum update -y
It is perhaps a good idea, after the doit script runs, to check the history to make sure no errors were noted:
[user@astronomy]$ /home/local/etc/doit-centos7 yum history
And then list any oddities in the below table --
**NOTE** - At 9:00am on 7-31-2020, Zach ran the doit script for CentOS7 machines. (this note is for me to track how long this process takes for a '''long''' update. Updates finished at ~3:30pm).
**Ran DO-IT centos7 script across all turned on machines on June 21st**

**NOTE** For AstroBackUp, AstroBackUp3, Cosmology1,4,5 -> you need to log in through the astronomy.nmsu.edu subnet and follow the GUI to update these machines.
====== Possible Issues ======
Some machines will not be able to update the kernel due to small partition sizes in /boot file system.
In order to clear up space:
First, use yum to check the kernel installed:
[root@machine ~]# yum list kernel
Then, figure out which kernel is the active one:
[root@machine ~]# uname -a
Then, use yum to remove kernels that is '''NOT''' the active kernal:
[root@machine ~]# yum remove kernel-old_version_number
Also, an additional work around is to just exclude the kernel in the update:
[root@machine ~]# yum update --exclude=kernel*
====== ISSUES ======
On 6-30-2021 Zach did an update to Hadar - In middle of the update, Hadar black screened and rebooted. This affected the display mainly (but other packages might have been affected). zach had to reinstalled package gdm (yum reinstall gdm).
