Azure File Sync - Server 2019 - Cloud Tiering not working on Deduplication Volume

    Question

  • We have a file server running Server 2019 Standard with GUI and the Azure File Sync Agent version 6.1. The data drive is set with deduplication enabled and it contains an Azure File Share with the Cloud Tiering enabled in the sync group server end point settings. 

    The server was in place upgraded from Server 2012 R2 with deduplication and Azure File Sync enabled, but cloud tiering not turned on before the upgrade.

    After the upgrade was complete Cloud Tiering was set to keep 90% of the drive free and cache everything that's not been accessed or modified in more than 1 day but no tiering appears to be happening. 

    The file sync agent log event 6004 is showing that all files are being skipped due to unsupported reparse point.

    Any suggestions on how to get tiering working without disabling deduplication and re-inflating the volume?

  • I just checked with the Service team, they mentioned a restart is required in order to be able to get tiering to work. Could you try a quick reboot on the server and check again ?

  • The server has been rebooted a number of times. I'm still seeing no tiering, and the events are the same.

    I've cleared out the GUIDs and server name etc. in an excess of paranoia.
