Hello, all!
We are in the process of re-engineering and virtualizing[0] the NFS
service provided to Toolforge and VMs. The transition will be rocky and
involve some service interruption... I'm still running tests to
determine exactly host much disruption will be required.
The first volume that I'd like to replace is 'scratch,' typically
mounted as /mnt/nfs/secondary-scratch. I'm seeking feedback about how
vital scratch uptime is to your current workflow, and how disruptive it
would be to lose data there.
If you have a project or tool that uses scratch, please respond with
your thoughts! My preference would be to wipe out all existing data on
scratch and also subject users to several unannounced periods of
downtime, but I also don't want anyone to suffer. If you have
important/persistent data on that volume then the WMCS team will work
with you to migrate that data somewhere safer, and if you have an
important workflow that will break due to Scratch downtime then I'll
work harder on devising a low-impact roll-out.
Thank you!
