Troubleshooting Global Data Platform issues

Warning: Do NOT delete IBM Storage Scale pods. Deletion of Scale pods in many circumstances has implications on availability and data integrity.
  • Delay between filesystem mount and IBM Storage Scale Container Storage Interface Driver (CSI) pods deployment
    Diagnosis
    CSI custom resource (CSO) status shows an error in getting the primary filesystem details. Run the following command to get the status: 
    oc describe cso -n ibm-spectrum-scale-csi
    Example output: 
    
Status:
  Conditions:
    Last Transition Time:  2023-06-06T07:10:08Z
    Message:               Failed to get the details of the primary filesystem: fs3
    Reason:                GetFileSystemFailed
    Status:                False
    Type:                  Success
    Resolution
    Delete only the CSI operator pod from ibm-spectrum-scale-csi namespace. For example, operator pod name ibm-spectrum-scale-csi-operator-7bd7f4654d-28h56.
    Verify whether the CSO status show Success as True. For example: 
    
Status:
  Conditions:
    Last Transition Time:  2023-06-06T07:11:16Z
    Message:               The CSI driver resources have been created/updated successfully
    Reason:                CSIConfigured
    Status:                True
    Type:                  Success
  • Backup of scale deployed application with static PV fails

    This is a IBM Storage Scale limitation. Snapshots can be taken only for certain types of IBM Storage Scale volumes. Volume Snapshot is supported only for the independent fileset based PVCs. For more information about the limitation, see IBM Spectrum Scale documentation.

    As a resolution, reconfigure IBM Storage Scale and IBM Storage Scale Container Storage Interface Driver for independent fileset PVCs and try again. For steps to reconfigure, see IBM Spectrum Scale documentation.

Known issues

  • The IBM Storage Scale limits to 10 pending snapshots at a time. If backups fail due to timeouts on snapshot requests, take a look at the state of the Scale cluster.
  • If you deployed IBM Storage Fusion to any custom namespace, the log collection package appears under the folder name ibm-spectrum-fusion-namespace. Instead, it must be under the custom namespace that is used in actual log collection.
