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.

Red Hat are detecting that a few of the default ciphers in the crypto-policies package they supplied in RHEL8 are now considered insecure.

Hopefully someone at Red Hat will see sense and update the crypto-policies to remove the insecure defaults.

This is on a RHEL 8.10 updated system.

I have successfully debugged a configuration issue on all of our #RHEL8 #Linux servers involving #rsyslog and #journald, and now I feel I've done enough for the day.

Does anyone here use brp_mangle_shebangs for #rhel8 rpm spec files? I am lost why my shebang excludes is not working 😐

Any help on syntax would be appreciated

The constant battle to keep #RHEL8 working in a production environment this last years has taken its toll.

I wish I could convince the powers that be to switch to #SUSE.

We are currently using #NFS for storage on our #k8s cluster. We are testing #OpenEBS now.

Because you mentioned many issues with #OpenEBS and none with #Longhorn , I think we need to take another look at #Longhorn and #Rancher.

I'm thinking I need a pull through cache for my home #kubernetes cluster, to speed up any restarts/redeployments of apps across the cluster. I'm using #rhel8 and #podman

Does anyone have any suggestions? In cluster would be nice, but not critical. Leaning towards just JFrog CR just because of using Artifactory in the past.

"For those relying on CentOS 8 to enjoy the reliability and features of Red Hat Enterprise Linux 8 but without the licensing costs, etc, that will end in 2021. "

So that's how #IBM thinks it'll make even more business with #GNU/#Linux.

I'm testing #CentOS #Stream and it is actually quite cool. But killing of the 1:1 rebuild from #RHEL8 sources is a mistake IMHO. A big mistake - at least if #RedHat won't provide a much more open access to the original #RHEL itself.
