Hi All,
I am in the process of implementing multi-site RGW instance and have
successfully set up a POC and confirmed the functionality.
I am working on metrics and alerting for this service, and I am not seeing
metrics available for the output shown by
radosgw-admin sync status --rgw-realm=<>
I'd totally defer to the RADOS folks.
One issue might be adding a separate code path, which can have all sorts of
problems.

Ok Anthony,
I understood what you said. I also believe in all the professional history and experience you have.
Anyway, could there be a configuration flag to make this happen?
As well as those that already exist: "--yes-i-really-mean-it".
This way, the storage pattern would remain as it

Hi,
Please consider not leaving this behind:
https://github.com/ceph/ceph/pull/55109
It's a serious bug, which potentially affects a whole node stability if the
affected mgr is colocated with OSDs. The bug was known for quite a while
and really shouldn't be left unfixed.

Hi,
Can anyone confirm that ancient (2017) leveldb database mons should
just accept ‘mon.$hostname’ names for mons, a well as ‘mon.$id’ ?
at some point you had or have to remove one of the mons to recreate it
with a rocksdb backend, so the mismatch should not be an issue here. I

I would just set noout for the duration of the reboot no other flags really
needed. There is a better option to limit that flag to just the host being
rebooted. which is "set-group noout " where is the servers
name in CRUSH. Just the global noout will suffice though.

Hi Janne, thanks for your reply.
I think that it would be good to maintain the number of configured replicas. I don't think it's interesting to decrease to size=1.
However, I think it is not necessary to write to all disks to release the client's request. Replicas could be recorded immediately
Hi Anthony,
Thanks for your reply.
I didn't say I would accept the risk of losing data.
I just said that it would be interesting if the objects were first recorded only in the primary OSD.
This way it would greatly increase performance (both for iops and throuput).

And as said before still it is in warning state with pgs not deep-scrubed
in time . Hope this can be ignored and set those two flags "noout and
nobackfill" then reboot .
Thank you again Sir

pause and nodown is not a good option to set, that will certainly make
clients stop IO. Pause will stop it immediately, and nodown will stop
IO when the OSD processes stop running on this host.
When we do service on a host, we set "noout" and "nobackfill", that is
enough for reboots, OS upgrades

Hi,
In reply to your question for this UUID thing, we do need it for CLONING
subvolume and yes, it is a requirement.
And the subvolume mount path is the entire directory path.

Can rbd image snapshotting be scheduled like CephFS snapshots? Maybe I missed
it in the documentation but it looked like scheduling snapshots wasn’t a
feature for block images. I’m still running Pacific. We’re trying to devise a
sufficient backup plan for Cloudstack and other things residing in
