You can look at /var/discourse/shared/log/rails/production.log (or something like that) and see the error.

Perhaps you need to

cd /var/discourse
./launcher enter app
rails c
# and then something like

But it could be coincidence that S3 backups has nothing to do with this and your disk is full.


thank you. i tried but i can not fix it. error log is below.

there is 5 GB free space.

I would disable the S3 settings from the rails console. I tried to give an example above. You might need to search here for some more examples

You did not set the s3_upload_bucket parameter.
Just do

cd /var/discourse
./launcher enter app
rails c
SiteSetting.s3_upload_bucket = 'thenameofyourbucket'

where you change the last line so it has the actual name of your S3 bucket.


thank you. that fixed the problem. But why this happened ? Because i only wanted use S3 for backups so i did not enter any butket for uploads. Is this normal or a bug ?

I can only reproduce this issue when enabling enable_s3_uploads.

I think this is what happened and which does result in an Oops screen:

  • you added s3 access key id and s3 secret access key
  • you configured an s3_upload_bucket
  • you enabled enable_3s_uploads
  • you set backup_location to s3
  • you had to set a s3_backup_bucket and you set it to the same bucket
  • this gives an error message You cannot use the same bucket for ‘s3_upload_bucket’ and ‘s3_backup_bucket’. Choose a different bucket or use a different path for each bucket.
  • you cleared s3_upload_bucket so you could use s3_backup_bucket
  • you did not turn off enable_s3_uploads

The bug is that enabling_s3_uploads requires an s3_upload_bucket, but emptying that setting while s3 uploads are still enabled crashes the forum.


anything we can do to fix the above @eviltrout?

There’s already a validation in place to prevent this:

But it doesn’t cover the case where you blank the bucket while leaving uploads enabled.


This should do it:
