Hi, Here is how I restore OVN DB. * Stop all ovn-nb-db, ovn-sb-db and ovn-northd services. * Clean up all DB files. * Start all DB services. Fresh ovn-nb-db and ovn-sb-db clusters are up and running. * Set DB election timer to 10s. * Restore DB to ovn-nb-db by ovsdb-client. * Start all ovn-northd services.
A few minutes after, ovn-sb-db is fully synced with ovn-nb-db. Now, the client of ovn-sb-db, ovn-controller and nova-compute complaint about "stale data". The chassis node is not getting updated. ======== 2020-08-04 09:07:45.892 26 INFO ovsdbapp.backend.ovs_idl.vlog [-] tcp:10.6.20.84:6642: connected 2020-08-04 09:07:45.895 26 WARNING ovsdbapp.backend.ovs_idl.vlog [-] tcp:10.6.20.84:6642: clustered database server has stale data; trying another server ======== Restarting ovn-controller and nova-compute resolve the issue. Is this expected? As part of the DB restore process, should I restart ovn-controller and nova-compute on all chassis node? Thanks!
