Logical Volume Conditions
Logical volumes are the core storage abstraction in simplyblock, representing high-performance, distributed NVMe block devices backed by the cluster. Maintaining visibility into the health, status, and performance of these volumes is critical for ensuring workload reliability, troubleshooting issues, and planning resource utilization. Simplyblock continuously monitors volume-level metrics and exposes them through both CLI and observability tools, giving operators detailed insight into system behavior.
Accessing Logical Volume Statistics
To access a logical volume's performance and I/O statistics, the sbcli-pre command line tool can be used:
sbcli-pre volume get-io-stats <VOLUME_ID>
All details of the command are available in the CLI reference.
The information is also available through Grafana in the logical volume's dashboard.
Accessing Logical Volume Health Information
To access a logical volume's health status, the sbcli-pre command line tool can be used:
sbcli-pre volume check <VOLUME_ID>
All details of the command are available in the CLI reference.
