looks like there is sth wrong with your cluster. And we suggest using https://github.com/kubernetes-csi/csi-driver-smb

Thanks Andy,

Using the plugin I was able to create the PV and the PVC 👍

I am not able to use the volume within a deployment :

              mountoptions: "vers=2.0,dir_mode=0777,file_mode=0777"   

I get the following message

MountVolume.MountDevice failed for volume "pv-smb" : rpc error: code = Internal desc = volume(publishingstudio_smb) mount "//172.16.1.43/publishingstudio$" on "/var/lib/kubelet/plugins/kubernetes.io/csi/pv/pv-smb/globalmount" failed with mount failed: exit status 32 Mounting command: mount Mounting arguments: -t cifs -o dir_mode=0777,file_mode=0777,vers=2.0,domain=172.16.1.30, //172.16.1.43/publishingstudio$ /var/lib/kubelet/plugins/kubernetes.io/csi/pv/pv-smb/globalmount Output: mount error(11): Resource temporarily unavailable Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Could you help me to understand what is wrong?

Regards,

Sébastien

to narrow down the issue, could you ssh to one agent node, and run

mkdir /tmp/cifs
mount -t cifs -o dir_mode=0777,file_mode=0777,vers=2.0,domain=172.16.1.30, //172.16.1.43/publishingstudio ... /tmp/cifs

Looks like there is sth wrong with your smb server.

[andyzhangx]

also you can use this way to create a smb server on k8s cluster: https://github.com/kubernetes-csi/csi-driver-smb/tree/master/deploy/example/smb-provisioner, that may narrow down the issue.
