Hi,
We are using octopus 15.2.7 for bucket sync with
symmetrical replication.
replication is asynchronous with both CephFS and RGW, so if your clients keep writing new
data into the cluster as you state the sync status will always stay behind a little bit. I
have two one-node test clusters with no client traffic where the sync status is actually
up-to-date:
siteb:~ # radosgw-admin sync status
realm c7d5fd30-9c06-46a1-baf4-497f95bf3abc (masterrealm)
zonegroup 68adec15-aace-403d-bd63-f5182a6437b1 (master-zonegroup)
zone 69329911-c3b0-48c3-a359-7f6214e0480c (siteb-zone)
metadata sync syncing
full sync: 0/64 shards
incremental sync: 64/64 shards
metadata is caught up with master
data sync source: 0fb33fa1-8110-4179-ae45-acf5f5f825c5 (sitea-zone)
syncing
full sync: 0/128 shards
incremental sync: 128/128 shards
data is caught up with source
