Maintaining OS Customizations After Software Upgrade
My LTM/GTM systems are running 10.2.0 on volume partitions, and there are a number of standard customizations we make to our F5 units during our build process. One simple example is that we create a directory named /usr/local/scripts, upload a couple files there, and add references to /etc/crontab. Another example is uploading a customized authorized_keys2 file to /root/.ssh to facilitate some management automation.
I haven't actually had to perform an upgrade yet, so I'm not completely sure how this process is supposed to work. But my understanding is that we install the new software to a non-active volume, and then boot to that new volume.
I'm wondering if any of my customizations will need to be performed after booting to the new volume? And if so, will they need to be performed every time software is installed to another volume, or only the first time? I have been looking for documentation that describes what is and is not retained during an upgrade, but haven't had much luck.
I'm also wondering about hotfixes - are hotfixes installed on the active volume? Or are those also installed to a separate volume?
Can someone flush this out a bit for me?
- hooleylistCirrostratusHi SMP,
- smp_86112CirrostratusHi hoolio, let me lay out a bit more of a concrete example. My question is sort of a combination of what happens to customizations I've made, but also what happens to the active configuration. Let's say I have this configuration:
- hooleylistCirrostratusThe config from the current slot is the one which is upgraded/installed on the newly upgraded/installed slot. So if you ran the installation onto MD1.3 from MD1.1 the 10.1.0 config would be installed on MD1.3. Your customizations would probably not get copied during the config save to a UCS file as they're probably not included in a UCS by default. If you wanted, you could modify that though:
