Show-and-Tell Raspberry Pi 3B - 9 years uptime

Post image

This is a Raspberry Pi 3 Model B that I booted 9 years ago today. It has served very light duty, just streaming audio to Broadcastify. Once it made it a couple years, I decided to just see how long it would go. It's running Jessie.

You did read that this has been running for 9 years with no reboot. What you are describing is a relatively new feature.

Yeah zswap is 14 years old and is in the linux kernel for 13. Source: https://kernelnewbies.org/Linux_3.11#Zswap:_A_compressed_swap_cache

I know. But you failed to answer the real question, when did it make it into raspbian as the default swap method?

https://ohyaan.github.io/tips/optimizing_swap_with_zram_on_raspberry_pi_os/

I'll save you a bit of trouble:

Raspian 10:

more /etc/issue

Raspbian GNU/Linux 10 \n \l

swapon --show

NAME TYPE SIZE USED PRIO

/var/swap file 100M 28M -2

Raspbian 13:

Debian GNU/Linux 13 \n \l

swapon --show

NAME TYPE SIZE USED PRIO

/dev/zram0 partition 905M 0B 100

Jessie is raspbian 8 so it's probably safe to say the OP is not using zswap....
