Mentioned in SAL (#wikimedia-labs) [2016-10-18T17:49:21Z] <madhuvishy> Rolling out https://gerrit.wikimedia.org/r/#/c/316482/ on maps instances for T147657

Maps migration details

Announcement:

The /data/project/maps NFS share is undergoing maintenance, starting 9 AM PST (16:00 GMT) and will be unavailable for a short window on 10/19/2016.

Post maintenance, there will be a change in the process for having /data/project/maps available to new instances added in future to the maps project. When a new instance is created, please notify the Labs team, ideally by making a phabricator ticket tagging project Labs, and we will have to make a small change to production puppet config, to have the share available on the new instance. Note that this is specific to maps and does not apply to existing instances.

Plan:

• Define maps as a labstore1003 mount [DONE]
• Mount maps from labstore1003 and 1001 - https://gerrit.wikimedia.org/r/#/c/316482/
• Remove the mount from 1001 (Removing defn from nfs-mount.yaml)
• Snapshot and latest sync of the maps share
• Symlink mount path - /mnt/nfs/labstore1003-maps/project to /data/project and /mnt/nfs/labstore1003-maps/home to /home on maps - Running puppet should bring back the share
• labstore::fileserver::replicate - Move to misc.pp
