[ceph-users] Re: Multi-site RadosGW with multiple placement targets

[Tobias Urdin]

Hello,
Thanks for the response!

So to support the use-case where I have the option to place data on one 
side and another replicated on both sides
I would need to have one zonegroup per side and then another zonegroup 
that spanned both sites?


Best regards

Placement targets aren't meant to control whether replication happens.
All zones need to provide mappings for any placement targets/storage
classes named in the zonegroup. Zones will fail to replicate
buckets/objects that they don't have placement rules for, and those
failures will be retried until they succeed. If they can't ever succeed,
then sync status will always show as behind, replication logs won't be
trimmed, and replication in other placement targets will be affected.

 Hello,

 I'm trying to wrap my head around how having a multi-site (two
 zones in
 one zonegroup) with multiple placement
 targets but only wanting to replicate some placement targets would
 work.

 Can you setup a zonegroup with two zones and it would only
 replicate the
 placement targets that the other side has?

 For example if we have three placement targets in the zonegroup, one
 zone got all three placement targets and the
 other zone only has two of them, would it only replicate the two?
