On Wed 26-Feb, we are making
a large change to how NFS is mounted in Cloud Services
https://gerrit.wikimedia.org/r/c/operations/puppet/+/571821.
This will impact any Cloud VPS projects that mount NFS for home
directories, project directories and scratch, including
Toolforge. During this change, NFS will become unresponsive for
a short time. Some NFS clients will recover on their own with
little impact. Where needed, WMCS will reboot or remount NFS
clients.
This change will improve future NFS management and hopefully
reduce future disruptions from maintenance.
