As part of the efforts to retire labstore1003 and move to more modern hardware with some redundancy, we will begin the process of switching the mounts for /data/scratch to the new server starting 2019-05-28. It is advised to not use the /data/scratch NFS mount during the maintenance, starting next Tuesday at 1800 UTC until after it is announced over, which should be around an hour, since the mount will be changing location and will be generally somewhat unstable.
NFS changes have occasionally caused more holistic problems within Toolforge in the past, but this should be fairly low-impact since it isn’t affecting /data/project or /home.
