I am running a Kubernetes cluster in GCP and using a local SSD as the persistent disk for a CouchDB service. I've checked today and the disk just disappeared, it is not accessible anymore and thus I can't access my data.

When I run lsblk to see the available disks I can't see it anymore. Checking the logs I see the recurrent error:

"storageclass.storage.k8s.io "manual" not found"

Anyone had faced a similar issue? Any hope of recovering my data?

Thanks in advance.

No, that disk is lost. GCP local SSDs are not persistent.

GCP disks can be persistent, it depends mainly how you define your StorageClass objects, when you claim for a new disk and use a StorageClass with the property reclaimPolicy: Retain, if you are not using StorageClass (you should be), you also have this option on PersistentVolume objects like described here: https://kubernetes.io/docs/tasks/administer-cluster/change-pv-reclaim-policy/
