Series | [ovs-dev,v8] ovsdb-tool: Convert clustered db to standalone db. | expand |
Hi Han and Ben: Sorry, realized little late that ovsdb-tool transact wont work on clustered db. Since in current UT I didn't add AT_CHECK for transact operation for clustered db, test-suite didn't catch the same. Hence, fixed it in v9 and merged it to one UT to use ovsdb-client to insert transaction for cluster db and then do the conversion and compare the data.
