My current opinion is that the problem lies with Cloudstack itself, not Ceph. I opened this thread here to rule out the rather unlikely possibility that the issue is related to Ceph storage.

Thanks for the links. The Cloudstack thread is actually mine, which I opened there in parallel. I will continue the discussion there..

CephFS has an upper file size limit which should be set to 1 TB by default. You can inspect the current value in `ceph fs dump`. Maybe Cloudstack is setting this to a lower values? Best regards, Burkhard
