critical

Resource ContentionUpdated Feb 23, 2026

Persistent volume usage (kubelet_volume_stats_used_bytes) approaches capacity while collections continue growing, risking write failures and cluster instability.

KubernetesSymptoms of this issue are visible in Kubernetes metrics and logs

How to detect:

Alert when kubelet_volume_stats_used_bytes / kubelet_volume_stats_capacity_bytes exceeds 80%. Cross-reference with collection_vectors and container_fs_writes_bytes_total to confirm vector data growth.

Recommended action:

Expand persistent volume claims, enable compression (qdrant_collection_config_params_product_compression), or implement data retention policies. Monitor Qdrant Cloud alerts for automatic scaling recommendations.
