How does it help with stuck PVCs?

It diagnoses whether the issue is caused by full OSDs, CSI provisioner failures, or storage class misconfigurations and provides specific remediation steps for each scenario.

What should I do when OSDs are at 85% capacity?

The skill recommends cleaning up unused PVCs and Released PVs or expanding capacity immediately, as 85% is the default threshold where Ceph may begin blocking writes.

Can I use this if I don't have rook-ceph-tools installed?

Yes, this skill provides methods to run Ceph commands directly through existing monitor (mon) pods, bypassing the need for dedicated tools pods.

What clusters does this skill support?

It is designed specifically for OpenShift clusters running OpenShift Container Storage (OCS) or OpenShift Data Foundation (ODF).

Diagnoses and remediates Ceph storage health issues within OpenShift OCS and ODF clusters.

This skill provides a comprehensive diagnostic framework for managing Ceph storage on OpenShift clusters using OCS or ODF. It enables developers and sysadmins to quickly identify cluster health states, troubleshoot stuck PersistentVolumeClaims (PVCs), manage OSD capacity, and resolve CSI provisioner errors. By providing direct command templates for mon pods and OSD maintenance, it simplifies complex storage management tasks and ensures cluster stability through proactive health checks and proven remediation patterns.
