The following options allow \fBovsdb\-server\fR to synchronize its databases with another running \fBovsdb\-server\fR. .TP \fB\-\-sync\-from=\fIserver\fR Sets up \fBovsdb\-server\fR to synchronize its databases with the databases in \fIserver\fR, which must be an active connection method in one of the forms documented in \fBovsdb\-client\fR(1). Every transaction committed by \fIserver\fR will be replicated to \fBovsdb\-server\fR. This option makes \fBovsdb\-server\fR start as a backup server; add \fB\-\-active\fR to make it start as an active server. .TP \fB\-\-sync\-exclude-tables=\fIdb:table[,db:table]...\fR Causes the specified tables to be excluded from replication. .TP \fB\-\-active\fR By default, \fB\-\-sync\-from\fR makes \fBovsdb\-server\fR start up as a backup for \fIserver\fR. With \fB\-\-active\fR, however, \fBovsdb\-server\fR starts as an active server. Use this option to allow the syncing options to be specified using command line options, yet start the server, as the default, active server. To switch the running server to backup mode, use \fBovs-appctl(1)\fR to execute the \fBovsdb\-server/connect\-active\-ovsdb\-server\fR command.
