This pages provides guidance for early adoption of CephFS by users with an appetite for adventure. While work is ongoing to build the scrubbing and disaster recovery tools needed to run CephFS in demanding production environments, it is already useful for community members to try CephFS and provide bug reports and feedback.
Please see the instructions at Ceph Filesystem.
For the best chance of a happy healthy filesystem, use a single active MDS and do not use snapshots. Both of these are the default:
The fuse client is the easiest way to get up to date code, while the kernel client will often give better performance.
The clients do not always provide equivalent functionality, for example the fuse client supports client-enforced quotas while the kernel client does not.
When encountering bugs or performance issues, it is often instructive to try using the other client, in order to find out whether the bug was client-specific or not (and then to let the developers know).
If you have identified a specific issue, please report it with as much information as possible. Especially important information:
If you are satisfied that you have found a bug, please file it on http://tracker.ceph.com. For more general queries please write to the ceph-users mailing list.
