Hi,
> As I can understand, we are talking about Ceph 15.2.x Octopus, right?
Yes i'am on ceph 15.2.4
> What is the number of zones/realms/zonegroups?
ATM i run just a small test on my local machine one zonegroup (global)
with a zone node01 and node02 als just one realm
> Is Ceph healthy? (ceph -s and ceph health detail )
ceph is fine on both clusters

user is the same:

yes without it metadata was in sync

i'll try
from my understanding it should be possible to write into the same
bucket on both clusters at the same time and it will sync with each
other?
also if i upload data (on the master, two files just around 100KB) it
takes a lot of time (10 min) until both sides are back in sync
data sync source: acff3488-0ae4-4733-8f8c-a90baf7d09e9 (global-node01)
syncing
full sync: 0/128 shards
incremental sync: 128/128 shards
2 shards are recovering
recovering shards: [71,72]
from my understanding that should be a lot faster?
Thanks,
Ansgar
