So the Nova blueprint is here [1] and I have proposed a (somewhat more
general) session for the summit here [2].

Since Nova now has a bit more elaborate BP process [3], will need to
post a review as well which will happen in the next few days.

I am not likely to have all the time in the world to work on this in
Juno... or any for that matter :). But I will be more than happy to
review patches coming in and help them land in case I do have to drop
this from my TODO list.

Thanks,

N.

I was going to propose that same thing for Nova as well, as well as a
summit session for Atlanta. Would be good to coordinate the work.

Would you be interested in looking at it from Cinder side?

Thanks,

N.


hi nikola:

Sounds great! very interested in collaborating to make a contribution
towards this effort.

Could you provide your bp and your summit session? I am willing to get
involved in the discussion and/or the design and implementation.


hi guys:

I have registered a bp for this issue from Cinder side.
https://blueprints.launchpad.net/cinder/+spec/send-volume-changed-notifications-to-nova
Lingxian and I will get involved in this implementation and collaborate 
with nikola.

It looks like this was a temporary accepted solution and the long term solution
is with event callbacks [1].

Re: [openstack-dev] [nova][cinder] create server from a volume snapshot, 180 reties is sufficient?

2014-04-08 Thread Solly Ross 
I think some of the objections to such patches were based on the fact that this 
is really
just a shortcut for two separate operations: create a volume from a Glance 
image, and then boot
off of that image.  Instead of monkey-patching it, we should either figure out 
a way to dynamically
configure the timeout based on image size, network conditions, etc, or we 
should just remove the shortcut
entirely, and just have people do the two steps separately (the current 
workaround for large disk images).

Solly Ross

Options may be bad, but hardcoded values chosen arbitrarily are worse. Unless 
someone can justify why the value needs to be 180 and not 179 or 181 then it 
should be configurable. That’s my opinion at any rate.

hi there: 





According to the patch https://review.openstack.org/#/c/80619/ , Nova 


will wait for volume creation for 180s, the config option is rejected by 


Russell and Nikola. But the reason I raise it up is, we found the server 


creation failed due to timeout in our deployment, with LVM as Cinder 


backend. 





So, I wander is 180s really suitable here? Are there some guidences

option, just because of the existing overwhelming number of them, right? 





Thoughts?
