[Labs-announce] [Wikimedia Labs][Announce] NFS (only labs projects) maintenance on 2017-01-18

[Madhumitha Viswanathan]

Hello,

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
migration.

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 -
https://phabricator.wikimedia.org/T154336. Let us know if you have any
questions or concerns on the list or on #wikimedia-labs.
