I'm not sure what that refers to -- maybe upgrading the NFS server's network connections? In any case, this maintenance is entirely unrelated to NFS. Details about the storage backend in question can be found here: https://techblog.wikimedia.org/2020/08/24/ceph-distributed-vm-storage-coming-to-cloud-services/On Oct 15, 2020, at 3:11 PM, Andrew Bogott <abogott@wikimedia.org> wrote:
On Monday at 14:00 UTC I'll be moving both toolforge bastions to the new storage backend. That will will result in downtime; everyone will be better off if you log off entirely before the window so that you don't lose work in progress.
It's only two hosts, but they are known by many names, including:
- stretch-dev.tools.wmflabs.org
- instance-tools-sgebastion-08.tools.wmflabs.org.
- dev.tools.wmflabs.org.
- dev.toolforge.org.
- login.tools.wmflabs.org.
- login-stretch.tools.wmflabs.org.
- bastion.toolforge.org.
- instance-tools-sgebastion-07.tools.wmflabs.org.
I'll send an another email after the move is complete.
