BMYSS1401

Disk capacity does not match on all the nodes.

Severity

Critical

User response

Do the following steps to resolve the problem:
  1. Run the following command to get the names of all nodes in the cluster.
    oc get nodes
  2. Run the following command for each node to check the disk capacity.
    oc debug node/<node_name> -- lsblk
    Example output:
    Temporary namespace openshift-debug-nrcbd is created for debugging node...
    Starting pod/compute-1-ru5rackm03rtpraleighibmcom-debug-8b2gq ...
    To use host binaries, run `chroot /host`

  3. Confirm that each node in the cluster contains the same disk configuration and capacity.
  4. If you find any discrepancies in disk sizes, then ensure that should be addressed and maintain uniform capacity on all nodes.
