<div>Thanks so much for the response. I want to be sure I understand your caveat about slave volume being larger—that is not intuitive. I’d think the slave volume could be the same size, that is, same useable space as seen by a fuse client. Where does a
larger slave volume size requirement come from, if I may ask?</div></div></blockquote><div><br></div><div>Well, slave *can* be of sma esize as master (useable space).

<div>I’d like to have a distributed-replicated master volume, and distributed-only slave.</div>
<div><br>
</div>
<div>Can this be done? Just beginning the research, but so far I’ve only done geo-replication with distributed-only volumes. Tips/caveats on this kind architecture are welcome.</div>

<div><br>
</div>
<div>Yes, This can be done. Both master and slave can be of different configurations.<br>
<br>
</div>
<div>But make sure that your slave volume has more effective size available than the master volume.<br>
<br>

<div>The rationale is straightforward—the master volume should be able to stay available with all data when suffering a node loss, but the geo-replicated volumes can be taken offline for repairs and resync as soon as possible.</div>
