Subject: [PATCH] ovn-ctl: Add support for ovsdb-server
|
|
|
5f9769 |
--disable-file-column-diff.
|
|
|
5f9769 |
|
|
|
5f9769 |
There is a change of a database file format in OVS version 2.15 that
|
|
|
5f9769 |
doesn't allow older versions of ovsdb-server to read the database file
|
|
|
5f9769 |
modified by the ovsdb-server version 2.15 or later. This also affects
|
|
|
5f9769 |
runtime communications between servers in active-backup and cluster
|
|
|
5f9769 |
service models.
|
|
|
5f9769 |
|
|
|
5f9769 |
For the upgrade scenario OVS introduced special command line argument
|
|
|
5f9769 |
for ovsdb-server: --disable-file-column-diff.
|
|
|
5f9769 |
More datails in ovsdb(7) or here:
|
|
|
5f9769 |
https://docs.openvswitch.org/en/latest/ref/ovsdb.7/#upgrading-from-version-2-14-and-earlier-to-2-15-and-later
|
|
|
5f9769 |
|
|
|
5f9769 |
In order to support upgrades of OVN databases introducing new option
|
|
|
5f9769 |
'--ovsdb-disable-file-column-diff' for ovn-ctl script that will pass
|
|
|
5f9769 |
aforementioned argument to ovsdb-server processes.
|
|
|
5f9769 |
|
|
|
5f9769 |
To simplify upgrades for users, ovn-ctl will add requested argument
|
|
|
5f9769 |
to ovsdb-server only if ovsdb-server actually supports it.
