Comment 27 for bug 1460653

Big Switch Networks,

env-1 failed due to network related issues:
2015-06-18 22:14:16.486 586 DEBUG fuel_agent.utils.utils [-] Got non-critical error when accessing to http://mirror.fuel-infra.org/mos/ubuntu/dists/mos6.1-updates/Release on 21 attempt: HTTPConnectionPool(host='mirror.fuel-infra.org', port=80): Max retries exceeded with url: /mos/ubuntu/dists/mos6.1-updates/Release (Caused by <class 'socket.gaierror'>: [Errno -3] Temporary failure in name resolution)

dns related issues. Please make sure that mirror.fuel-infra.org could be resolved from a master node.

logs for env-2 interrupts in the middle of process, but the process was running at the moment of time of snapshot taking. I didn't see any errors.

It looks like your network bandwidth is really enough. The another thing which may slowdown the process of image building is I/O operations. deboostrap and apt-* tools make use of a lot of unnecessary fsync() calls. Combined with filesystem mount options them could take a lot of time.

accodring to the previous snapshot, building of images took at least 1.5h
So, i highly recommend you to
1) start deployment
2) wait until it fails by timeout (1h)
3) wait at least additional 30mins
4) check that the following files appeared on a master node:
/var/www/nailgun/targetimages/env_{ENV_ID}_ubuntu_1404_amd64.img.gz
/var/www/nailgun/targetimages/env_{ENV_ID}_ubuntu_1404_amd64-boot.img.gz
5) start re-deploy of the same env with {ENV_ID}. It should not fail.
