In order to make the NFS it works on more resilient and healthy, the cluster it runs on is migrating to DRBD failover like Tools home and project uses. The current setup is quite broken.
If you are running something against scratch when the patch becomes active in your project, you may see some issues like a stale NFS handle. If that doesn’t resolve quickly, please let us know in Libera.chat: #wikimedia-cloud
