Continuing the storage redundancy and reliability efforts for Labs (
https://phabricator.wikimedia.org/T126083), the final migration to the new
NFS storage cluster for Labs projects with NFS enabled is upcoming. The
migration is planned to happen 2017-01-18 starting 09:00 PST(16:00 UTC).
This *does not* affect tools, maps or any other projects that don't have
/home or /data/project mounted. The migration window is expected to be
fairly short (<3 hours) - but could last up to 6 hours.

During the migration, no new data will be written to NFS (/home or
/data/project), but existing data will be accessible in Read-only mode for
the most part. Post migration, any services or jobs that were running on
top of NFS (/home or /data/project) will require manual restarts. Jobs
running on top of /scratch or /public/dumps will be unaffected. I will keep
the lists and #wikimedia-labs updated on progress during and after the

The list of labs projects that will be affected in this migration are:

   - catgraph

   - account-creation-assistance

   - contributors

   - wikidata-topicmaps

   - sugarcrm

   - wikidumpparse

   - video

   - openstack

   - testlabs

   - wikidata-dev

   - quarry

   - huggle

   - editor-engagement

   - utrs

   - wmt

   - cvn

   - fastcci

   - toolsbeta

   - project-proxy

   - dumps

   - bots

   - snuggle

   - math

   - wikisource-tools

The tracking task on phabricator is here -

questions or concerns on the list or on #wikimedia-labs.
