i'm having similiar issues

andyzhangx commented 3 weeks ago

this error means the nfs csi driver is not installed or registered correctly on your cluster, pls provide controller logs follow by: https://github.com/kubernetes-csi/csi-driver-nfs/blob/master/docs/csi-debug.md#case1-volume-createdelete-failed

luckury commented 2 weeks ago

How many PVs are in your cluster overall? We had a similar issue where we "exhausted" the amount of PVs that the cluster can hold with the NFS CSI driver. It seems to be 20 per (worker) node. Could be similar/same issue as in #649

I'll leave this as a reference for the devs since this NFS driver does not support this option?! https://github.com/container-storage-interface/spec/blob/master/spec.md#nodegetinfo

I get a similar issue of Dynamic Volume Provisioning. Is there anyone who could provide some tips what's going wrong here? Here is my log for your reference:

@Ryan-ZL-Lin that's because you are using drivername=nfs2.csi.k8s.io in nfs csi driver controller? if you want to change the drivername, you also need to change the provisioner in storage class.
