Hi Félix, Could you please send me the output of the "ceph report" command (privately, the output is likely too big for the list) ? I suspect what you're seeing is because the smaller disks have more PGs than they should for the default.rgw.buckets.data pool. With the output of "ceph report"

[ceph-users] How to calculate the nearfull ratio ?

Hi, In a cluster where the failure domain is the host and dozens of hosts, the 85% default for nearfull ratio is fine. A host failing won't suddenly make the cluster 99% full. In smaller clusters, with 10 hosts or less, it is likely to not be enough. And in larger clusters 85% may be too much
