No restrictions about Volume type in Slave side. But when a Slave
node<br>
is down, some of the files already created are not accessible so
data<br>
operations/sync may fail for those files.(These errors will be
logged<br>
in Master log files and Geo-rep will continue.).<br>
<br>
Other problem is deleting files in Slave side may get ignored
silently<br>
in Geo-replication because Geo-rep treats "ENOENT" errors as safe<br>
errors during delete/unlink. (Safe error because, Geo-rep tried to<br>
delete a file and that file gets "ENOENT"(No such file/directory)<br>
error). Due to this Slave Volume may have files which are deleted in<br>
master.<br>

<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>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>
