Production Linux App Service deployment content filesystem failure.

Region:

Poland Central

The currently running application remains healthy, but all new ZIP deployments fail while writing to /home/site/wwwroot.

Last successful deployment:

b349e758-f0eb-43ca-94bb-f9dab3ddecca

2026-07-29T19:28:47Z

Failed OneDeploy deployments:

ca18e424-2f48-47a9-9fce-c5597b97cbce

e5ce8639-3db1-4c41-9510-f38ffc5aa511

Failed QuickDeploy deployments:

3a0c92c6-a915-489c-92e5-9eb3a8a546ab

5e2d62e5-d466-4040-8d14-2fa38c2f5530

OneDeploy was explicitly run with clean=false and restart=false.

Both OneDeploy and QuickDeploy extract the valid ZIP successfully, but fail copying files to /home/site/wwwroot.

OneDeploy repeatedly reports:

rsync: [receiver] open "/home/site/wwwroot/<dll>" failed:

No such file or directory (2)

rsync exit code 23

QuickDeploy without server-side build reports:

File sync failed, using fallback method

Could not find file '/home/site/wwwroot/Azure.Security.KeyVault.Keys.dll'

FileSystemUsage dropped from approximately 185.6 MB to 24.4 MB during the incident. The running worker and /health endpoint remain healthy, likely because the previous assemblies are already loaded.

Please investigate and repair the App Service content share or Kudu filesystem. Do not restart, stop, scale, or recycle the running production worker without coordinating the recovery plan, because /home/site/wwwroot may be incomplete.

EVERYTHING WAS WORKING CORRECTLY BEFORE YOU CHANGED AZURE PORTAL DEPLOYMENT CENTER UI. FIX IT IMMEDIATELY!!!!
