GitLab.com runs the same GitLab as our users and some upgrades require downtime. Other operations should not require downtime, we have multiple application servers and load balancers. The backend services are HA except the file storage until we complete the move to CephFS.

Why did you guys choose Ceph instead of OpenStack Swift? Just curious.

    IIRC there was an issue (in Ceph) with performance in the case of many small files. Is that solved now?

    Swift only provides object storage and we need block storage.
