Image Artist: "Not enough MinIO storage left" message during Upload or Harmony Transfer

Problem:

Upload jobs fail with the following error:

Not enough MinIO storage left in order to proceed with upload. Storage left: X %

Cause:

In order avoid storage saturation, Image Artist prevents Upload jobs if the available disk space is less than 10%, as defined by the MINIO_LOW_STORAGE_LIMIT variable found in the default.env file. 

MINIO_LOW_STORAGE_LIMIT=0.1

The following locations are bound by the MinIO low storage limit:

• /var/lib/docker/volumes  (the default location for Docker defined volumes).
• Any custom mount point, as defined by either the MINIO_VOLUME_PATH (Image Artist version 1.3 or lower) or MINIO_VOLUME_PATH_NEW_FS (Image Artist version 1.4) variables in the .env (hidden) file located in the Image Artist installation directory.

Solution:

The recommendation would be to increase the disk allocation of the affected filesystem, or remove unnecessary files to free space. 

Alternatively, the MINIO_LOW_STORAGE_LIMIT can be lowered by adding a line to the custom.env (override) file found in the Image Artist installation directory. 

MINIO_LOW_STORAGE_LIMIT=0.01

In the above example the low storage limit is set to 1%, where Upload and Harmony transfer jobs would be prevented if the available storage is less than this value. 

The Image Artist stack must be redeployed for this change to take effect: Image Artist: How do I redeploy/restart the container stack?
