radosgw-admin sync status output
All; We've been running our Ceph clusters (Nautilus / 14.2.8) for a while now (roughly 9 months), and I've become curious about the output of the "radosgw-admin sync status" command. Here's a the output from our secondary zone: realm <guid> (<realm-name>) zonegroup <guid> (<zonegroup name>) zone <guid> (<zone name>) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: <guid> (<master zone name>) syncing full sync: 0/128 shards incremental sync: 128/128 shards 3 shards are recovering recovering shards: [39,41,66] Radosgw is in use, so the active recovery for data doesn't really surprise me. What I am curious about is these 2 lines: full sync: 0/64 shards full sync: 0/128 shards Is this considered normal? If so, why have those lines present in this output? Are they relevant to a different type of replication than what we are doing (I'm not aware of a different type of radosgw replication, but I'm not omniscient)? Thank you, Dominic L.

It seems normal because my multisite's status shows like that too. I'm curious about the output as well. <DHilsbos@performair.com> 于2020年6月11日周四 上午1:09写道：

This appears to be normal. My interpretation is those numbers show how many shards are currently syncing, so it would be intentional that the full sync numbers slowly go down to 0 as the full sync progresses through the shards and the incremental sync numbers stay up since the incremental sync is continuously running for all shards.
That is my experience as well. The full sync will only run after initiating a data or metadata sync init. On Thu, Jun 11, 2020 at 9:30 AM <swild@tiltworks.com> wrote:
