Hey all,
I've gotten a couple requests in the past 24 hours asking how to
"lock"
the new dev machines
https://wiki.sepia.ceph.com/doku.php?id=hardware:vossi
These systems aren't in paddles so `teuthology-lock` isn't going to work
here. Is that something you all want?
My understanding is, historically, the rex and senta have been shared
machines where there is a chance devs can step on each others' toes. I
get the desire to have exclusive use of a machine but I don't want to
have to be the one to police machine-hogging.
Yeah I don’t think we want to lock them. Is there a specific reason
people are asking?
Nope
If we want to do stuff that involves changing the machine state for more
than adding new package dependencies, we should be working in containers
or VMs...
It sounds like the concern is multiple devs running `make` at the same
time slowing each other down.
Yeah we'll just have to learn to be polite to each other on that score.
We divvied up the rex boxes once upon a time to try and keep load on
them relatively even and then worked out how many cores we could
usually take. I guess the vossi are different distros so that's a
little weird (though I don't know if anybody cares?), but perhaps we
can do a wiki sign-up or something for them as well.
