Run radosgw-agents in test mode.
|
|
|
|
Configuration is clients to run the agents on, with settings for
|
|
source client, destination client, and port to listen on. Binds
|
|
to 0.0.0.0. Port defaults to 8000. This must be run on clients
|
|
that have the correct zone root pools and rgw zone set in
|
|
ceph.conf, or the task cannot read the region information from the
|
|
cluster.
|
|
|
|
By default, this task will start an HTTP server that will trigger full
|
|
or incremental syncs based on requests made to it.
|
|
Alternatively, a single full sync can be triggered by
|
|
specifying 'sync-scope: full' or a loop of incremental syncs can be triggered
|
|
by specifying 'sync-scope: incremental' (the loop will sleep
|
|
'--incremental-sync-delay' seconds between each sync, default is 30 seconds).
|
|
|
|
By default, both data and metadata are synced. To only sync
|
|
metadata, for example because you want to sync between regions,
|
|
set metadata-only: true.
|
|
|
|
An example::
|
|
|

tasks:
|

- ceph:

client.1:
