What in the world is wrong with this machine?

Something as simple as syncthing running, an apt upgrade, or even just doing a dd of a gigabyte from /dev/zero to a junk file can cause the system load to scream up to 10 (quad-core system), and it starts freezing.

Do I have a dodgy SSD???

Update 1: I am using full disk encryption (LUKS)

Update 2: gsmartcontrol output https://bin.benjaminhollon.com/fersimebia

Update 3: I'm going to try copying everything over to a spare SSD later.

Look at this (during a 1GB dd):

22:15:29 up 1 day, 14:27, 1 user, load average: 0.99, 1.26, 1.53
64934
22:15:56 up 1 day, 14:28, 1 user, load average: 7.05, 2.66, 1.98
64934

The load just explodes in a single second

@RL_Dane
From my experience, every random issue an os re-install doesn't fully resolve is at least partially storage related.
What does Gnome Disks say about the SMART data?
Also how full are your partitions, how old is the drive, and has there been a recent steady increase in unexplainable buggy behaviour?
I just had something very similar happen and it was definately the SSD.

Will tell you as soon as I can get anything new to launch. XD XD XD

And it is a fresh install.

@RL_Dane
Do it from a live usb.
Also take backups using the live usb and a separate drive if you still need to.

@RL_Dane
Fedora's live usb comes with gnome disks, so do many other distros.
Here are instructions for viewing SMART data:

I'll definitely be booting from a live USB. I have done live system migrations before (dding a running disk to another machine -- before VMWare and containers became common), but that's REALLY rolling the dice. XD

@RL_Dane Are you using disk encryption or software raid?

I've used both, and I do not recommend either for this and other reasons. Especially not both at once.

Also make sure you've got plenty of free space. Modern file systems absolutely freak the hell out if you don't have plenty of free space.

@OpenComputeDesign

I always use full disk encryption.

Disk usage is <40%

@RL_Dane @OpenComputeDesign
Full disk encryption seems to exasperate ssd issues...

@Linux_in_a_Bit @OpenComputeDesign

Any idea why that is?

@RL_Dane @OpenComputeDesign
More reading and writing among other things I guess, not really sure though, just seems to be the case from too little experience.

@RL_Dane I'm not saying it's definitely related to the encryption. On account of I'm a know nothing moron with no right to say anything for sure.

But I've had no end of problems with disk encryption. But then, I'm a know nothing moron, so that is the expected thing to happen with anything I touch.
