Expanding the Raspberry Pi file system

colporteur

Does anyone have a quick history lesson so that I avoid a full chase the squirrel engagement, on the A1 Expand Filesystem option, under the Advanced Options in the raspi-config tool?

 

I stumbled across a suggestion to expand the file system while researching a project. Instead of fully engaging and chasing this squirrel, I thought someone in the community might just have a quick answer.

 

I recall at one point in Raspbian (RP OS) development the operating system would indicate it was expanding the filesystem and then reboot. I don't recall seeing that message lately. Does the automatic SD card expansion still exist? Does the option described above utilises the full capacity of any SD card installed or are their limits?

 

I confess this is me being lazy but still curious of the answer. Any response off the top of your head?

    While waiting for an E14 webinar to start I took a few minutes to resolve my question.

     

    I used two SD cards a 16G and 32G for this test. I formatted them with RP OS 2020-05-27. When installed the full size of the card capacity was available in the file system without having to perform any actions.

     

    I'm not sure what the raspi-config menu option mentioned in my post provides. It appears the O/S uses what ever the card capacity is to set up the file system. I did notice the 32G card on first boot took a little while longer to respond to an ssh connection. I'm going to assume it was working on the file system formatting for a larger SD card.
