Azure WebJobs: There is not enough space on the disk

问题

I've tried zipping up a console app and uploading it to Azure as a WebJob, as I've done with others, but the upload fails. No explanation is given.

So then I tried FTPing it up there. I put it in

/site/wwwroot/App_Data/jobs/triggered/FeedbackNotifications

Where "FeedbackNotifications" is the name of my WebJob. I took the path from this site.

The upload completes and I can see the WebJob listed in the Azure portal. However, when I click "Run once" it fails. The log file contains the following:

The total size of the directory that contains everything is 115MB.

I've also read this page which suggests that long file names may be the cause of the fault, but I've no file names longer 69 characters.

UPDATE: I've noticed that when I try an additional WebJob which previously worked, it incurs the same error.

回答1:

When the WebJob is invoked the first time (or when its binaries are updated), it is first copied to the %TEMP% directory and will run from there.

Free (sku) azure websites have a limited amount of disk space in the Temp directory (actually in d:\local) which is 500MB. It seems you have reached it and so WebJob fails to start.

To verify you can go to your scm site's debug console (https://{sitename}.scm.azurewebsites.net/DebugConsole) and query for the free space on d:\local (pushd d:\local or clicking on the Earth button).
