LVM question - Lemmy.World
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 to 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?

What are some of the most upgradable laptops in the past ~5 years? - Lemmy.World
This is a bit of a selfish post, but I don’t think I’m the only one out there
interested in this. I’m in the market for a more recent laptop, my most recent
laptop is from 2017, and boy have I been burned in the past by laptops that look
good on paper, but end up being pretty disappointing in their design and
upgradability. I don’t need a high powered machine, but what I do want is the
ability to increase or replace ram, storage, etc. These aren’t usually hard to
find, but I do feel like finding a laptop with those upgradable components while
also being well designed is a bit more difficult to come by. I am currently
having a blast upgrading my extremely old IBM X31 (2003, mine since 2006) and in
opening it up it’s just a joy to see things laid out in an easy to maintain,
accessible, and efficient (functionally and with respect to maintenance) manner.
There are minimal shortcuts made to handle thermal characteristics, vents are
placed where cool air should be brought in instead of just someplace convenient,
and ram and other components are easy to replace. Surely there have been some
laptops made in the last 5 years that also have these characteristics, but in my
research it’s real hard to find out which ones they are. So my question to you
Lemmings who often take apart and maintain laptops, what would you consider to
be the best designed laptops for longevity and maintenance that have come out
recently?

Thinking of a career change - Lemmy.World
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.
RP2040 uses - Lemmy.World
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.
