If you are trying to mount an external folder to Domino, these admin docs should help you through the process: https://admin.dominodatalab.com/en/4.6/data-management/external-data-volumes.html#overview
Occasionally we'll see some issues come up which can be difficult to troubleshoot. Here's one of the errors we've seen come up in this process:
kernel: CIFS VFS: cifs_mount failed w/return code = -22
If you see that error, please verify whether worker nodes from your autoscaler have cifs-utils installed. If you continue to struggle with the network mapping, please reach create a ticket with the support team that includes steps you have already taken, and any error messages you are seeing from your system.
