Upgrade Enterprise Linux c версии 7 на версию 8 с сохранением данных

Давно уже наступил срок End of Life у Enterprise Linux 7, но возможно на ваших серверах он еще есть в работе. Затягивание процесса переноса могло произойти по разным причинам: сложные процессы миграции, необходимость в дополнительных мощностях для маневра, длительность процесса переноса, зависимость от бизнес-процессов заказчиков. Зачастую upgrade ОС на месте — самый удобный способ. В данной статье я описываю инструменты и трудности, с которыми вы можете столкнуться в процессе.

I guess I f'd up when I installed my #rhel8 #vm to replace the #rhel7 one I had for myself at work. /boot couldn't install the latest kernel since it was too large. Even after deleting the only other kernel aside from the latest I was running off of, it was 19MB short.

Looking into it, the consensus was a lot of fearmongering about not touching it and just reinstall the OS. Yeesh. Sure, just do it again and get all my settings together again, no problem.

*DISCLAIMER*: Maybe don't do this unless you are willing to burn your system and start over from scratch (or better yet, reload your snapshot/backup you took before you did this, amirite?)

I just said "f it" and downloaded a #gparted live cd, popped it in the VM after adding 1GB (yeah, I know, overkill for /boot) to storage, then dragged that partition over that unallocated space. #vmware #rhel #linux #sysadmin #sysadminlife #sysadminproblems

📆 Seit 2014 füllt die Version 7 von Red Hat Enterprise Linux (RHEL) zahlreiche Server mit Leben. Ende Juni 2024 endet der planmässige Unterstützungszeitraum, und damit die Verfügbarkeit von Softwareaktualisierungen. Dasselbe Schicksal erwartet auch den Community-Ableger CentOS 7.

Wow, the web #Spotify interface really sucks moose balls. The native Linux program I used to love that was useful no longer works. On RHEL 7 I have little option so I need to use the web interface. When I get a chance to update to RHEL 8, there are native Spotify apps that will work. Updating my primary workstation to RHEL 8 is going to put me out of work for a couple days though. This may be a thing to save for a couple weeks after the semester ends.
