Unable to delete or create volumes in HCI environment

Solution In Progress - Updated -

Issue

  • We are unable to create or or delete volumes. This is an outage for the environment. We need to get the environment back up. We tried rebooting the entire environment, but had no success. The environment looks healthy. pcs cluster status, docker containers on controller look to be running, ceph is healthy.

  • Ceph status is HEALTH_WARN and many PGs statuses are unknown:
