Check Storage Utilization

Purpose

Check utilization of local storage PVC, Ceph-based storage PVC, and the S3 bucket. When a health-check shows abnormal disk pressure or pods crash due to disk issues, you can check storage utilization to pinpoint the issue.

Action

Log in to the Linux root shell of a cluster node and use the following commands:

• For the local storage PVC—paragon-local-volume-check

• For Ceph-based storage PVC and S3 bucket—paragon-ceph-usage-check [-h] [-s] [-c] [-b]

  Where:

  • -h or --help displays command usage information.

  • -c or --cephfs checks Ceph-based storage usage.

  • -s or --s3 checks S3 bucket usage.

  • -b or --both checks both Ceph-based storage and S3 bucket usage.

Sample Output

• paragon-local-volume-check
• paragon-ceph-usage-check -h
• paragon-ceph-usage-check -s
• paragon-ceph-usage-check -c
• paragon-ceph-usage-check -b

Meaning

The paragon-local-volume-check command lists all the PVCs, the local path, disk usage, and size of a PVC, as well as the node on which the PVC is located.

The paragon-ceph-usage-check command displays a detailed view of the Ceph filesystem with the usage, capacity, claim name, and PV name, as well as the volume location.
