Re: [Openstack-operators] How to tune scheduling for "Insufficient compute resources" (race conditions ?)

Thanks a lot George It looks like this indeed helps ! Cheers, Massimo 2016-11-30 16:04 GMT+01:00 George Mihaiescu : > Try changing the following in nova.conf and restart the nova-scheduler: > > scheduler_host_subset_size = 10 > scheduler_max_attempts = 10 > > Cheers, >

How many nova-schedulers are you running? You can hit this issue when multiple nova-schedulers select the same compute node for different instances. Belmiro On Wed, Nov 30, 2016 at 3:56 PM, Massimo Sgaravatto < massimo.sgarava...@gmail.com> wrote: > Hi all > > I have a problem with scheduling

Hi Belmiro We are indeed running 2 nova-schedulers, to have some HA Thanks, Massimo 2016-11-30 16:18 GMT+01:00 Belmiro Moreira < moreira.belmiro.email.li...@gmail.com>: > How many nova-schedulers are you running? > You can hit this issue when multiple nova-schedulers select the same > compute

Try changing the following in nova.conf and restart the nova-scheduler: scheduler_host_subset_size = 10 scheduler_max_attempts = 10 Cheers, George On Wed, Nov 30, 2016 at 9:56 AM, Massimo Sgaravatto < massimo.sgarava...@gmail.com> wrote: > Hi all > > I have a problem with scheduling in our

Hi all I have a problem with scheduling in our Mitaka Cloud, Basically when there are a lot of requests for new instances, some of them fail because "Failed to compute_task_build_instances: Exceeded maximum number of retries". And the failures are because "Insufficient compute resources: Free
