Hi all. I’m currently running a home server using Ubuntu OS, but I’d like to try and explore other options for operating systems to better my skills with linux/unix.
Currently I’m considering switching to Fedora server (though feedback is welcome) because I’ve been running it as my daily OS for a few months now and I quite like it. I’m also looking at Debian server because that’s what my old professor used and he did nothing but speak its praises.
Only issue is I’m concerned about data loss from moving the installation. Currently, the server is setup to run several Docker images running my programs. While moving over the images shouldn’t be difficult whatsoever, I’m afraid my storage setup might not be so easy. Currently, it’s two 4TB hard drives running in a logical volume. I’d love to simply be able to move over all the files to a backup drive, but I don’t have anywhere I can store >5TB of files as a backup.
I googled around, but I couldn’t find too many guides on migrating logical volumes. The one or two I did find were most definitely written for someone with far more linux knowledge than I have as a relative noob, so any advice would be extremely welcome!
Another point to keep in mind - many distros now ship Podman instead of Docker, with Fedora being at the forefront of that change. If you‘re currently running Docker, you might want to check if your setup is drop-in compatible with Podman as some images will not work (usually related to permission or user switching, privileged ports).
Yeah, I was gonna try and check on that as well pretty soon! Thanks for the alert!
