4.3のTechnology Preview Featuresであるマルチサイトの機能を試してみます。
それではまたいつものように手探りで設定してみます。

リモートサイト追加

まずはremote-site-addでCLUSTER1からCLUSTER2に向けてリモートサイトを設定します。

> remote-site-add --address 10.10.107.202

オブジェクトストレージ追加

両方で同じオブジェクトストレージを追加する。その際に--sharedを忘れないようにする。

動作確認

CLUSTER1での更新がCLUSTER2でも反映されていることが確認できました。

ほんのちょっと遅れて（それでもF5を押せば一瞬待たされるがすぐ反映されてた）他方に反映されています。
どっちを更新してももう一方に反映されます。アクティブ－アクティブですね。

    --remote-share-size                     A share size limit (quota) for the new remote share (defaults to the local share's size)
    --remote-share-size-warning-threshold   Threshold (1-99 percent) for the new remote share's capacity usage, an event will be sent if this threshold is reached.
    --remote-share-unmapped-group           Default group name for new remote share, if there is no mapping discovered into the preferred domain (defaults to the local share's unmapped-group)
