On Masters

On each master node, run as root:

oc get nodes --show-labels

Output example:

Exported Filesystems

On the support node run exportfs and make sure the following filesystems are exported:

/storage/registry
/storage/metrics
/storage/logging
/exports/logging-es-ops

Docker Logs

Log into a few nodes and take a look at the docker logs:

journalctl -f -u docker
