Overview
As an nxtStore administrator, you are responsible for deploying and operating the distributed storage cluster that underpins block, object, and file storage for all NxtSight tenants. This guide covers cluster architecture, pool and CRUSH map management, storage tier configuration, capacity planning, encryption, monitoring, and common operational procedures.Topics
Architecture
Distributed storage cluster components — MON, MGR, OSD, MDS, RGW — and how they
work together to provide unified storage.
Cluster Management
Monitor cluster health, manage service placement, add and remove OSDs, and perform
day-to-day operational procedures.
Pool Management
Create and configure replicated and erasure-coded pools, set application types, and
manage existing pool settings.
CRUSH Maps
Define failure domains, device class rules, and data placement topology across
nodes, racks, and data center rooms.
Storage Tiers
Configure multi-tier storage with NVMe, SSD, and HDD device classes. Generate
volume types and Cinder backends via the nxtStore Storage Design System.
Capacity Planning
Monitor utilization, plan expansion, and maintain minimum capacity headroom to
ensure continuous cluster health.
Monitoring
Key metrics, alert thresholds, and nxtRadar integration for continuous cluster
health and performance visibility.
Security
Encryption at rest, cluster authentication, cephx key management, and
network isolation for production deployments.
Troubleshooting
Diagnose and resolve cluster-level issues — HEALTH_WARN states, OSD failures,
slow requests, and PG inconsistencies.
