export a virtual filesystem to the Linux kernel. It also aims to provide a

implementations.

Details about issue

I have a ~/.aws/credentials file and I am hoping s3fs to use it. I already looked at /var/log/syslog, there was nothing for s3fs. I'm not sure where else to look. Thanks for your help.

s3fs supports using credentials from ${HOME}/.aws/credentials as well as /etc/passwd-s3fs and $HOME/.passwd-s3fs.

~/.aws/credentials supports different profiles. The profile "default" is used by s3fs if no other profile name is choosen with -o profile <other profile>.

Example:

# cat ~/.aws/credentials
[default]
aws_access_key_id = XXXXXXXXXXXXXXXXXXXX
aws_secret_access_key = AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
[test42]
aws_access_key_id = YYYYYYYYYYYYYYYYYYYY
aws_secret_access_key = BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

Your s3fs command line doesn't contain -o profile <other profile>. Therefore, please check if you have a "default" profile in your ~/.aws/credentials like show in the example above, please.

I have a credential file with a default profile as shown above but I still get this error

Could the -o profile option use the value of the AWS_PROFILE environment variable, that is also used by the AWS CLI? This behavior would feel more intuitive.
