I have a stateful set with 3 replicas. The pods mount the following flexvol

      volumes:
        - flexVolume:
            driver: microsoft.com/smb
            options:
              mountoptions: 'vers=3.0,dir_mode=0777,file_mode=0777,,uid=1000,gid=1000'
              source: //sc.intra/data/backup/K8s/optimize
            secretRef:
              name: smbcreds-optimize
          name: elasticsearch-backup

While the mount of the flexvol works fine on 2 of the pods, on one it does not work

MountVolume.SetUp failed for volume "elasticsearch-backup" : mount command failed, status: Failure, reason: Failed to mount device at /var/lib/kubelet/pods/1cb0afbf-43a8-4ca5-9282-d8a6130a1e02/volumes/microsoft.com~smb/elasticsearch-backup, user:XXXX, //sc.intra/data/backup/K8s/optimize, error log:Refer to the .staticx.prog(8) manual page (e.g. man .staticx.prog)

In the logs of the affected node, I can see this

kernel: CIFS VFS: cifs_mount failed w/return code = -13

Any suggestion what could cause this problem and how I can debug/fix it?

Error code 13 usually means 'permission denied'

Yes I know, unfortunatley it still does not explain why it should work on 2 of 3 nodes. It's the same smb endpoint and same user for authentication

It could be wrong permissions on the mount point, it could be the node itself not having permissions to access the share.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
