Hi Magnus,
Thanks for the reply. Just to be certain (I’m having a slow day today), it’s the amount of data stored by the clients. As an example. a pool using 3 replicas and a quota 3TB : clients would be able to create up to 3TB of data and Ceph would use 9TB of raw storage?
Yes, but remember it's "client side security". So if the client does not play well nicely (malicious intent / buggy), it can ignore quotas. So make sure you have checks in place so you notice this. Of course depends on the threat model you have. FYI, Gr. Stefan
