From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Advice on migrating from Ubuntu server to another server OS (sh.itjust.works)

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!

I think basically all Linux distros will support lvm? It seems like some installers do not, but as long as you leave the disks alone during installation it should be fine. As for distro, Debian is a great choice for a server. I've had no issues over the years since I ditched Ubuntu since they keep moving towards commercialization. If you want to learn more compared to Ubuntu you might not learn much though. Fedora could offer more learning, though honestly it's kind of all the same.

Yeah, they definitely support it, I'm just worried about things being overwritten by the install
