systemd service not working on raspberry pi

[hobyte]

Expected Behavior

minio running after starting the systemd servicce

Current Behavior

starting minio through systemd fails

pi@raspberrypi:/etc/systemd/system $ sudo systemctl start minio
Job for minio.service failed because the control process exited with error code.
See "systemctl status minio.service" and "journalctl -xe" for details.

Apr 20 20:52:06 raspberrypi systemd[1]: Failed to start MinIO.

Possible Solution

It has to be something with ExecPreStart command in the minio.service file, but don't know how to solve this

Steps to Reproduce (for bugs)

1. Install RaspberryPi OS (64 bit)
2. Download the minio arm64 image, placing it in /usr/local/bin/ , make it executable
3. create the config
4. Place the provided minio.service file in /etc/systemd/system/
5. enable the service: sudo systemctl enable minio
6. start the minio service: sudo systemctl start minio

Context

At the Moment, I wan't to get minio running on a raspberry pi, to later use it as a backup for longhorn in my kubernetes cluster

Regression

Your Environment

Version:

$ minio --version
minio version RELEASE.2021-04-18T19-26-29Z

config:

$ ls -l /etc/default/
-rw-r--r-- 1 root root  257 Apr 20 20:30 minio
$ cat /etc/default/minio 
# Volume to be used for MinIO server.
MINIO_VOLUMES="/mnt/"
# Use if you want to run MinIO on a custom port.
MINIO_OPTS="--address :9199"
# Root user for the server.
MINIO_ROOT_USER=Root-User
# Root secret for the server.
MINIO_ROOT_PASSWORD=Root-Password

Service:

$ ls -l /etc/systemd/system
-rwxr-xr-x 1 root root  920 Apr 20 20:32 minio.service

Does this user have write access to /mnt?

chown -R minio-user:minio-user /mnt

Did you create this user? and provide permissions for this user to write to /mnt ?
