Storage Account Quota Issue

Lewis MacCallum 1

We are facing an issue where a file handle is being created every 2 minutes on our File Share for 3 different IP's. We have 3 Linux Web Apps with that file share mounted so I am assuming that the issue is related to these 3 web apps.

The problem is, after X amount of time we hit an error where we exceed our quota and the mounts fail and therefore our 3 Web Apps fail as they cannot access the files they need to.

Any help is appreciated on this.

@Lewis MacCallum
Can you please provide the exact error you are seeing as well as details on how you have mounted Azure Files?

I have attached the 2 images which are screenshots of errors we encountered when we faced the issue. We then ran the Get-AzStorageFileHandle cmdlet after some initial research into the issue pointed us in that direction and we were flooded with File Handles all had the same File ID, no path and at 2 minute intervals. We then cleared all of the File Handles and monitored them after and found that 3 IPs were getting a new file handle every 2 minutes and the old ones were not disappearing.

The mounts were mounted through the Azure Web portal with the interface provided.

In our recent platform upgrade we updated the Ubuntu version on Linux workers which internally had the updated CIFS driver used to mount the File Share. We have discovered certain issues with the updated CIFS driver which caused this file handle issue. Azure Product Team have found a fix and are currently deploying it globally. I recommend manually clearing these until the fix has been deployed.
