Subject [jira] [Commented] (CLOUDSTACK-9114) restartnetwork with cleanup should not update/restart both routers at once
Date Fri, 23 Mar 2018 13:14:00 GMT


ASF GitHub Bot commented on CLOUDSTACK-9114:

rhtyd opened a new pull request #2508: CLOUDSTACK-9114: Reduce VR downtime during network
   ## Description
   <!--- Describe your changes in detail -->
   Note *WIP*, but working for both non-redundant and redundant network VRs :)
   Every time there is a major CloudStack version that requires a new systemvmtemplate, admins
need to restart VRs which can take few (sometimes several) minutes. The aim of this project
is three parts:
   - Reduce systemvmtemplate size, see #2506. Smaller the image size, faster it will be to
copy template to primary storage to provision new VR.
   - Perform rolling reboot/deployment of VRs, by provisioning new VRs first and then killing
old ones.
   - Make isolated VRs future proof (have keepalived+conntrackd preconfigured TBD)
   - Refactor systemvm python code to speed up VR programming or rule application
   - Speed up iptables and misc rules application from the VR's .json files
   - Move away from iptables, move to nftables
   - Move away from Python2 codebase to Python3 or something else like Go? TBD
   [ ] Implement rolling reboot for VPC based on #2436 
   [ ] Speed up iptables and rules application based on #2083 
   <!-- For new features, provide link to FS, dev ML discussion etc. -->
   <!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. -->
   ## Types of changes
   <!--- What types of changes does your code introduce? Put an `x` in all the boxes that
apply: -->
   - [ ] Breaking change (fix or feature that would cause existing functionality to change)

   - [ ] Bug fix (non-breaking change which fixes an issue)
   - [ ] Enhancement (improves an existing feature and functionality)
   - [ ] Cleanup (Code refactoring and cleanup, that may add test cases)
   ## Screenshots (if appropriate):
   Screenshot shows ping drops from a guest VM, in a non-redundant isolated network: (2-5
ping drops observed)
   ![screenshot from 2018-03-23 17-53-46](
   In case of rVRs, 0-1 ping drops are observed

> to reduce the downtime of network, we'd better restart the RVRs one by one.
