Hi-
I am trying to get a better understanding of how Swift recovers from
failure. I've read the documentation, but the process is still somewhat
unclear.
I have a simple 5-node Swift cluster deployed with a replica count of 3 (3
zones and 2 handoff zones for a total of 5). I load the cluster with
some test data, and then on one of the nodes I shutdown swift and rsync. I
then purge the account, container, and object data from the node I
shutdown. When I start swift back up again on the purged node, how can I
detect that replication has completed and the missing data has been
restored to the node that I purged?
Thanks in advance for your assistance.
