We are starting this maintenance.  NFS services (and thus Grid and Kubernetes) could see short disruptions.  As long as all goes well, this should be minimal and only one server failover should be necessary, however, NFS is central to the setup and could cause difficulties if problems ensue.

We will be performing some updates (including reboots) on the tools NFS servers for Toolforge and CloudVPS instances that use project NFS (with the exception of dumps) at 1500 UTC on Wed Aug 29.  The maintenance window will be two hours and more than one NFS server failover is expected during that time.  This could cause some temporary impact to performance and load on the various connected servers during failovers.
