OK, with luck I will not confuse further.
You say:
The contents of your shared /data/project or /home directories will
not be immediately available in eqiad.
Yep. eqiad labs is, for now, a blank slate.
Does it mean that if I decide to move the content by hand, using SCP,
it will be overwritten anyway sooner or later?
No. Indeed, you are encouraged to move that content by hand -- just
please coordinate with us so we know what you're doing.
How do I decide if I
want to have this content moved by ops or by myself? What if I want to
move just some items from /data/project and remaining data can be
safely nuked?
The next two weeks are designated for you to do exactly that -- move
files by hand, and select which things to abandon. This is strongly
encouraged! Once you're done and ready to abandon other files please
make a note to that effect on the migration progress page (
https://wikitech.wikimedia.org/wiki/Labs_Eqiad_Migration_Progress ).
If in two weeks there's no note on that page and I see that your eqiad
shared dirs are still empty then I'll make a unilateral copy of everything.
(There's one caveat here: Because the file copies are going to take a
super long time, I've already started a job that will haphazardly copy
files over to eqiad and stow them in obviously-named subdirs, e.g.
'glustercopy' or 'nfscopy'. Those are there to save time as part of a
future migration... you should leave them be but otherwise ignore them.
If you opt for self-migration then you or I can just erase those dirs
later on if you have them.)
I hope this makes sense! Please let me know if I'm still being unclear.
