Re: Timeout during image build (task Networking)

  Thread Previous • Date Previous • • Thread Next
Turns out my issue was a borked run of Tempest that left a nova-ensure_bridge.lock file around. After manually destroying this lock file, Tempest is running cleanly again.
I'll look into adding a forcible removal of this lockfile to the unstack.sh script (which I personally use to reset my Devstack envs) 

Thanks,

Sorry, paste fail on the last message.

This seems like a likely culprit:

I'm guessing it only happens on concurrent builds? We probably need a
synchronized somewhere.

cc'ing Vish on this, as this is now occurring on every single devstack
+ Tempest run, for multiple servers.

Vish, I am seeing the exact same issue as shown below. Instances end
up in ERROR state and looking into the nova-network log, I find *no*
errors at all, and yet looking at the nova-compute log, I see multiple
timeout errors -- all of them trying to RPC while in the
allocate_network method. Always the same method, always the same
error, and no errors in nova-network or nova-api (other than just
reporting a failed build)

Any idea on something that may have crept in recently? This wasn't
happening a week or so ago, AFAICT.

Best,
-jay

I'm receiving RPC timeouts when trying to launch an instance. My
installation is the Essex release running on Ubuntu 12.04.

When I launch a test image, the launch fails. In my setup, Nova network
runs on a controller node, and all compute instances run on separate,
dedicated server nodes. The failure is repeatable. Upon examining the
various logs, I see the following (see below). Any insight would be
welcome.

From 'nova show <instance name>' I read the following:
