Re: [Openstack] veth pair disappear after hardware reboot

[varun bhatnagar]

Hello Mike,

Thanks a lot for replying.
No, I am not aware about veths not surviving a reboot. Is it mentioned in
any document of OpenStack?

I have checked the Neutron services and they are absolutely fine after
reboot. This problem is seen even when I kill/stop the network services and
again try to start them.

Could you please tell me if there is any fix for this?

BR,
Varun

Re: [Openstack] Cinder, custom filters and weighers.

[Thomas Zilio]

Hello Xinyuan,

The cinder scheduler is running on only one machine (the controller).
cinder.scheduler.filter_scheduler.FilterScheduler' is correctly set in 
cinder.conf.

Thanks,
Thomas

Re: [Openstack] [ANN] OpenStack Kilo on Ubuntu fully automated with Ansible! Ready for NFV L2 Bridges via Heat!

[Jose Manuel Ferrer Mosteiro]

 

Nice job. I am doing a vmware vcenter like in
https://github.com/elmanytas/ansible-openstack-vcenter [7] and I solved
the problem of duplicate endpoints in line 106 of
https://github.com/elmanytas/ansible-openstack-vcenter/blob/master/etc_ansible/roles/keystone/tasks/main.yml
[8] . This makes playbooks idempotents. 

Maybe you could be interested.

Did you change policy?

Use can have multiple roles, so admin, _member_ and heat_stack_user 
(while strange) could all be assigned to the same user.  You might need 
both depending on your setup.

[Openstack] [Summit] Selection process

[Nicholas Chase]

I'm working on an article about the summit talk selection process and 
some possible improvements.  I'd be interested to hear from people both 
for and against the current process so I can write a balanced take on 
it.  I don't want to clog up the list, so please feel free to contact me 
offline.


Thanks!

[Openstack] Slow Horizon on Icehouse.

[Ken D'Ambrosio]

Hey, all.  I've got an Openstack install, with each control node on its 
own 24 GB, quad-core system.  And yet my Horizon is really quite slow; 
I've seen it take 15+ seconds to log in, click on the "routers" tab, 
etc.


The only host among the control nodes that showed significant pain was 
the MySQL host; I replaced its SATA disk with an SSD last night, and now 
instead of a load average ~1.65, it's now around 0.10.  And things feel 
marginally better, but it's still darn slow, so I'm guessing the primary 
bottleneck was *not* MySQL.


Any suggestions on what I should be digging into?  Logs in the cloud 
controller box?  Known API bottlenecks?


Thanks!

-Ken

Try looking at your keystone table, not sure how old your stamp is but

I appreciate the thought, Steve, but I'd actually given that a try 
before installing the SSD.  I'd had ~100K entries in the token table, 
and brought it down to ~25K.  Just now, I did some more pruning, and 
have it to ~2500, and it's still slow as molasses logging in and 
clicking stuff.


I tried doing a tcpdump on the cloud controller, but, aside from the 
fact that interaction with horizon is slow (which I already knew), 
nothing really stands out.  (If it matters any, on my tcpdump, there are 
two five-second pauses in interaction with Horizon.  I tried to find 
five-second pauses in other interactions, e.g., with keystone, or MySQL, 
to no avail.)

Re: [Openstack] Slow Horizon on Icehouse.

[George Mihaiescu]

Is it just dashboard that's slow?
How about "nova list" or "neutron port-list" from your dashboard node, as
well as from outside your environment?

Depending on how you have your endpoints configured in keystone (ip or
name) and how dns resolution is set in your environment, there might be
delays in the api calls...

Thanks for the sanity check, George.  You know -- I've gotten so used to 
thinking in terms of performance and GRE tunnels and other abstractions 
that sometimes I just forget to look at the physical layer... where, 
yes, the dashboard node was dropping ~20% of its packets.  Bad port or 
cable (haven't checked which, yet).


Wups.

Don't understand why I didn't see massive retransmits in the pcap, but I 
guess I'm not going to worry myself with that too much.


Thanks, all,

-Ken

Hey, all.  I've got an Openstack install, with each control node on

its own 24 GB, quad-core system.  And yet my Horizon is really quite
slow; I've seen it take 15+ seconds to log in, click on the "routers"
tab, etc.


The only host among the control nodes that showed significant pain

was the MySQL host; I replaced its SATA disk with an SSD last night,
and now instead of a load average ~1.65, it's now around 0.10.  And
things feel marginally better, but it's still darn slow, so I'm
guessing the primary bottleneck was *not* MySQL.


Any suggestions on what I should be digging into?  Logs in the cloud

controller box?  Known API bottlenecks?


Thanks!
