early next week.
Welp, it turns out we need to accelerate this too. I’ve got to turn
stat1002 off today. So! Get it at while it is good! :)
I will be shutting stat1002 late this evening US east coast time.

Some other issues are accelerating this timeline for stat1002.
All /home directories from stat1002 have been synced to stat1005. In
addition, non-productionized data that was in /a has been synced to
stat1005 in /srv/stat1002-a.
I have also stopped various user cron jobs that were accessing /a on
stat1002. If you had something running there that isn’t puppetized, please
migrate it to stat1005 as soon as you can.
stat1002 will remain online at least until September 1st, but we need to
unmount the drive that contains both /home and /a partitions. /a and /home
on stat1002 (as they are now) will no longer be accessible early next week.
If you can’t find something on stat1005 that you were used to finding on
stat1002, please let me know and I will help you find it.
Thanks! Apologies in advance if this inconveniences anyone.

tl;dr: Stop using stat100 by September 1st.
We’re finally replacing stat1002 and stat1003. These boxes are out of
warranty, and are running Ubuntu Trusty, while most of the production fleet
is already on Debian Jessie or even Debian Stretch.
stat1005 is the new stat1002 replacement. If you have access to
stat1002, you also have access to stat1005. I’ve copied over home
directories from stat1002.
stat1006 is the new stat1003 replacement. If you have access to
stat1003, you also have access to stat1006. I’ve copied over home
directories from stat1003.
I have not migrated any personal cron jobs running on stat1002 or
stat1003. I need your help for this!
Both of these boxes are running Debian Stretch. As such, packages that
your work depends on may have upgraded. Please log into the new boxes and
try stuff out! If you find anything that doesn’t work, please let me know
by commenting on https://phabricator.wikimedia.org/T152712
Please be fully migrated to the new nodes by September 1st. This will
give us enough time to fully decommission stat1002 and stat1003 by the end
of this quarter.
I’ve only done a single rsync of home directories. If there is new data
on stat1002 or stat1003 that you want rsynced over, let me know on the
A few notes:
- stat1002 used to have /a. This has been removed in favor of /srv. /a
no longer exists.
- Home directories are now much larger. You no longer need to create
personal directories in /srv.
- /tmp is still small, so please be careful. If you are running long
jobs that generate temporary data, please have those jobs write into your
home directory, rather than /tmp.
- We might implement user home directory quotas in the future.
Thanks all! I’ll send another email in about a months time to remind you
of the impending deadline of Sept 1.
