LightSync patch on OpenStack Swift

How to Deploy Patch:

Requirement:

This patch requires OpenStack Swift Icehouse installed and should be applied on all storage nodes.

Deployment:

1. Locate the swift Python package

   This can be done by running Python, then executing:
   >>> import swift
>>> swift.__path__
   

   On our cluster the output is ['/usr/lib/python2.7/dist-packages/swift'],
   Which means the swift package location is /usr/lib/python2.7/dist-packages/swift

2. append the obj directory to swift package location

   This give swift-package-location/obj. in our cluster will be /usr/lib/python2.7/dist-packages/swift/obj

3. Patching

   Copy patch files(replicator.py and diskfile.py) to the extended path(/usr/lib/python2.7/dist-packages/swift/obj), replacing the existing ones.

4. Restart Openstack Swift object-server and object-replicator

   swift-init restart object-server object-replicator
