Not really. Logically it's not a difficult operation, there's just no code to do it. There was a patch a while back, but I guess it wasn't ever approved: https://review.openstack.org/#/c/5484/ > - reading about the "unique-as-possible" feature in folsom im asking myself > how would swift know if nodes are in different places, is there a feature > like "regions" i am not aware of? There's no concept of regions (yet). The commit message is pretty descriptive: https://github.com/openstack/swift/commit/bb509dd863dc99c06a232d1d8e0f950a7e73dcc8 > - after migration of data and having two replicas spread over those two > nodes, how can i make sure that in the event of a node beeing down swift > will not start copying files to second drives on the healty nodes? Swift won't over-replicate when a node's down, only when an individual drive is unmounted. There's no way to disable over-replication in that case, though. - Michael _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
