My locally hosted Discourse suddenly stopped working this morning. I tried to run ./launcher rebuild app and got the following error:
The partition was originally 20GB but I used gparted to expand it to 80GB:
So why is the error still showing the size at only 18GB and what can I do to fix it? I’ve already tried the cleaning docker images and containers option.
What does
df -h /
and
df -h /var/lib/docker
say?
I think that it’s possible to resize the partition without resizing the filesytem, thought I was pretty sure that gparted would do the Right Thing.
This is likely more of a Stack Exchange question than a Discourse question.

It looks like that partition is not where Docker lives. How about
mount
You probably need to move /var/lib/docker to that Discourse partition.

Gparted only increased the backing partition and maybe the volume group. You will also need to resize the logical volume and the filesystem.

Worked perfectly! Thank you so much! I’m finally back up and running again.
