Hello
Short question regarding journal-based rbd mirroring.

a. Create an event to describe the update
b. Asynchronously append event to journal object
c. Asynchronously update image once event is safe
d. Complete IO to client once update is safe

Dear Ceph Experts,
The docu about this rgw command is a bit unclear:
radosgw-admin bucket check --bucket --fix --check-objects
Is this command still maintained and safe to use? (we are still on nautilus)
Is it working with sharded buckets? and also in multi-site?
I heard it will clear

Hi Frederic
For your point 3, the default_storage_class from the user info is apparently
ignored.
Setting it on Nautilus 14.2.15 had no impact and objects were still stored with
STANDARD.
Another issue is that some clients like s3cmd are per default explicitly using
STANDARD.

Dear All,
RGW provides atomic PUT in order to guarantee write consistency.
cf: https://ceph.io/en/news/blog/2011/atomicity-of-restful-radosgw-operations/
But my understanding is that the are no guarantee regarding the PUT order
sequence.
So basically, if doing a storage class migration:

Dear All
The rgw user metadata "default_storage_class" is not working as expected on
Nautilus 14.2.15.
See the doc: https://docs.ceph.com/en/nautilus/radosgw/placement/#user-placement
S3 API PUT with the header x-amz-storage-class:NVME is working as expected.
But without this header RGW

Hi Wissem
Thank you for your reply.
As the erasure-code-profile is a pool setting, it is on a lower layer and rgw
should be unaware and independent of it, but it could play role regarding this

Anyway this does so seem to be the cause here; after
