Storage-ACK for writes after how many replica?
Hello Ceph-Users, I looked up in the docs but could not find a information about: * When does a storage-client get a write-acknowledgement Example: Replicated Pool 3/2 Will the write-ack come after reaching min-size or when all copys are written. Would be great if this could be added in the docs somewhere (maybe I did not find it - and its already there?). Thanks, Greetings Jonas

All copies. If you had a super slow drive then it could have tons of writes that are endlessly queueing to get written but never arrives to the magnetic media, while all clients are told everything is fine and you have the required amount of replicas. -- May the most significant bit of your life be positive.
Check out Figure 4 on page 7: https://ceph.io/assets/pdfs/weil-ceph-osdi06.pdf Respectfully, *Wes Dillingham* On Wed, Oct 29, 2025 at 8:16 AM <jsterr@proxforge.de> wrote:
