Hi all, I'm playing around with LVMs to expand data storage and I'm looking at what would be required to transfer those drives to another device, all the steps I can find require exporting the volume group and then importing on the other device. But what would be the case if your boot drive were to fail, and you needed to move the drives without being able to export the volume group. Can you just do an import with a new device, or are there other steps required to do so?

Secondly, is there a benefit to creating an LVM volume with a btrfs filesystem vs just letting btrfs handle it?

Hi sysadmins, I am thinking of doing a pretty drastic career change. I have 10+ years of experience in chemistry doing bioanalysis and a few years repairing breath alcohol analyzers. I have always considered messing around with electronics, networking, and computers/servers as a hobby and have been using various Linux distros as my main os for almost 20 years.

I have come to see my specialty in my line of work as a dead end. I'm pretty damn good at my job but I feel like automation is going to be taking over very soon, and I'm not that good that I think I'll be in the top 10% that get to stick around and run the automations when the robots finally take over. So I'm considering doing a career change to IT/sysadmin.

What I'd like to know is what should I learn how to do to see if I'll even like moving down this path? What can I set up at home, break, then fix that would give me an idea as to what the sysadmin life is really like?

I'm pretty sure I haven't ever really done any sysadmin type work with my home setups, seeing as I build and set up services I want for myself and at the level I'm willing to put up with. For the most part I can be handed something already implemented and work within that space to keep it going and adjust it to what I want it to do or fit my set up. I can usually find my way through log files and error codes to figure out what the problem is and duckduckgo my way to a fix.

Alright meshers, I've been playing around with meshtastic for some time now and I've ended up with a good number of devices. I'm mostly in the rakwireless boat, with a pair of heltecs.

I have two RP2040 (rak11310) units that I just can't come up with a good use for. They use less power than a heltec on full blast, but don't have Wi-Fi or Bluetooth. If you disable Bluetooth and Wi-Fi on the heltec and turn on power saving, the heltec ends up using less power for what I can see as the same capabilities as the RP2040.

So, what can I put these units to use for? The processor is definitely more powerful than the NRF52 boards, but meshtastic doesn't seem to need any more than the NRF52 has to offer. With power saving, the heltecs can perform equally well with less power, while also having a more powerful processor in case it's needed.
