1. mount error on Windows

  • error details:
FailedMount: MountVolume.MountDevice failed for volume "pvc-2ca92cca-c690-4fea-842f-0a4d32e97f5a" : rpc error: code = Internal desc = volume(pvc-2ca92cca-c690-4fea-842f-0a4d32e97f5a) mount "\\\\40.64.101.43\\share" on "\\var\\lib\\kubelet\\plugins\\kubernetes.io\\csi\\pv\\pvc-2ca92cca-c690-4fea-842f-0a4d32e97f5a\\globalmount" failed with smb mapping failed with error: rpc error: code = Unknown desc = NewSmbGlobalMapping failed. output: "New-SmbGlobalMapping : A specified logon session does not exist.

  • Workaround To mount a SMB share on Windows, domain name should be provided in account, could use a dummy domain name, e.g. Domain\AccountName

2. mount error on Windows after reboot

  • Workaround

Only use root share for one SMB server in one cluster and use subPath in deployment, if there is already \\smb-server\share\test1 mounted, would get error when mounting volume \\smb-server\share\test2 after Windows node reboot. Workaround is only use \\smb-server\share as source.

I will add notion in the windows example doc, there is no fix for this issue currently. Thanks.

  • Mitigation if hit Multiple connections to a server or shared resource by the same user error

log on to the Windows node, run Get-SmbGlobalMapping to list all mappings, run Remove-SmbGlobalMapping -RemotePath xxx to remove existing mapping, after a while, pod remount would succeed automatically
