For example:<br>
<br>
volume ns-afr0<br>
type cluster/afr<br>
subvolumes remote-ns1 remote-ns2 remote-ns3 remote-ns4<br>
end-volume<br>
<br>
Anything written to ns-afr0 will be AFRed to all the 4 subvolumnes.<br>
So how many copies you want to get, how many subvolumnes you should set.</blockquote></div></div><div><br>Thanks for the example.<br><br>By this approach you mean that basically the only way to define 2-way replication for example, is to put 2 bricks inside a volume?<br>
What if I have say 10 bricks and still need only 2 copies? I will need to define such sub-volumes for each pair?</div></div></div></div></blockquote><div><br>you can have two unify of 5 bricks each and have these two as children of afr. something like,<br>
<br>volume unify-0<br>type cluster/unify<br>subvolumes n1 n2 n3 n4 n5<br>end-volume<br><br>volume unify-1<br>
type cluster/unify<br>
subvolumes n6 n7 n8 n9 n10<br>
end-volume<br>
<br>volume afr<br>type cluster/afr<br>subvolumes unify-0 unify-1<br>end-volume<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<div dir="ltr"><div class="gmail_quote"><div class="gmail_quote"><div><br><br>This sounds a bit strange, because then you basically limited to 2 servers instead of to the whole server pool.<br>
<br>Is it possible just to add all available bricks to list, then specify how many copies to store?<br><br>Regards.<br></div></div></div></div>
