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
Zitat von "Szabo, Istvan (Agoda)" <Istvan.Szabo@xxxxxxxxx>:
Hi,
I’ve never seen in our multisite sync status healthy output, almost
all the sync shards are recovering.
What can I do with recovering shards?
We have 1 realm, 1 zonegroup and inside the zonegroup we have 3
zones in 3 different geo location.
We are using octopus 15.2.7 for bucket sync with symmetrical replication.
The user is at the moment migrating their data and the sites are
always behind which is replicated from the place where it was
uploaded.
I’ve restarted all rgw and disable / enable bucket sync, it started
to work, but I think when it comes to close sync it will stop again
due to the recovering shards.
Any idea?
Thank you
