Describe the running environment

A Centos7 vm connecting to a non-AWS S3 provider, based on OpenStack and CEPH

Mountpoint options

export AWS_ACCESS_KEY_ID=xxxxxxxxxxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxx
export AWS_ENDPOINT_URL=https://mys3.data

mount-s3   --region=Default --force-path-style --allow-delete --allow-overwrite --upload-checksums=off  --dir-mode=0777 --file-mode=0666 --allow-other  mybucket   /my_local_dir -d -f

What happened?

Attempted to copy a file to the bucket throws i/o error when closing the file. The file is actually well-written (verified by sha256sum checksum).

cp -f testfile_100M.bin /my_local_dir/
cp: overwrite ‘/my_local_dir/testfile_100M.bin’? y
cp: failed to close ‘/my_local_dir/testfile_100M.bin’: Input/output error

Hello, thank you for making this report. From the logs, it appears that your S3 implementation is returning a 412 precondition failed response to Mountpoint. Running with --debug --debug-crt should help verify that.
