Signals Image Artist: "MinIO storage is too low" error during Batch Analysis

Problem:

Batch Analysis jobs fail with the following error:

MinIO storage is too low (X %) in order to start batch analysis

Cause:

In order avoid storage saturation events, SImA prevents Batch Analysis jobs if the available disk space is less than 10%, as defined by the MINIO_LOW_STORAGE_LIMIT in the default.env file found in the SImA installation directory. 

MINIO_LOW_STORAGE_LIMIT=0.01

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 (SImA version 1.3 or lower) or MINIO_VOLUME_PATH_NEW_FS (SImA version 1.4) variables in the .env (hidden) file located in the SImA 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 file found in the SImA installation directory. 

MINIO_LOW_STORAGE_LIMIT=0.01

In this example the low storage limit is set to 1%, where Batch Analysis jobs would be prevented if the available storage is less than this value. 

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