[Engineering] Upcoming move of users from stat1005 to stat1007

[Luca Toscano]

Hi everybody,

as part of https://phabricator.wikimedia.org/T205846 we are going to ask to
all the stat1005's users to move to stat1007 during the next two weeks. The
deadline is November 14th, by which time ssh access to stat1005 will be
removed.

Background: on stat1005 we have a GPU (more details in
https://phabricator.wikimedia.org/T148843) that has been sitting there for
almost two years, and it would be great to try to make it work during the
next months. This effort will require a lot of tests/reboots/etc.. that can
of course impact ongoing work of all of you, so we prefer to move everybody
to another identical machine beforehand.

Please reach out to me or to the analytics team in T205846 or IRC
(#wikimedia-analytics on Freenode) if you have any
questions/doubts/blocker/etc.., we are not going to enforce the deadline if
anybody will raise concerns or blockers of course. It would be great to
move everybody by Nov 14th but we surely don't want to disrupt any ongoing
important work.

I am going to update the Wikitech documentation about stat1005 and stat1007
as soon as possible, for the moment keep in mind that stat1007 will take
over completely everything that stat1005 currently does.

I have already copied over all the stat1005 directories to stat1007, and
I'll periodically sync them during the following days. If you don't find
anything important, please add a note in T205846.

Thanks a lot and sorry for the trouble,

Luca (on behalf of the Analytics team)
