Azure File Sync - Cloud Tiering policy not working

Question

I've installed the Azure File Sync Agent on a 2012 R2 server, created the sync group and enabled Cloud Tiering with a 20% free space policy. 1.3TB has synchronized up to the Azure File Share but it's been several days and still only 1% free on the server endpoint. No errors and nothing in the Tiering event log. I manually tiered a file using the invoke-storagesynccloudtiering command and that worked fine. Any clues as to why the Cloud Tiering Policy is not working?

Additional info - if I use the command line to check HeatStore like Get-StorageSyncHeatStoreInformation -FilePath 'filepath' I get an error Get-StorageSyncHeatStoreInformation : Element not found. (Exception from HRESULT: 0x80070490) I tried several different commands. Almost like the HeatStore does not exist.

Answer 1

We had 25gb free disk space. After disabling Cloud Tiering, adding disk space and then reenabling Cloud Tiering it is now working.

Answer 2

@Cathy Leik Thanks for the email we are checking on it! In mean while can you refer to the suggestion mentioned below.

The data we are looking is not found in sync DB. Mostly happens when file is not yet synced and we are attempting to ghost, Wait for some time for file to be synced and the syncdb populated.

There are two paths for failures in cloud tiering:

• Files can fail to tier, which means that Azure File Sync unsuccessfully attempts to tier a file to Azure Files.
• Files can fail to recall, which means that the Azure File Sync file system filter (StorageSync.sys) fails to download data when a user attempts to access a file which has been tiered.
