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.
