Inktank is not yet supporting it because we do not have the QA in place and general hardening that will make us feel comfortable recommending it for customers. That said, it works pretty well for most workloads. In particular, if you stay away from the snapshots and multi-mds, you should be quite stable. The engineering team here is about to do a bit of a pivot and refocus on the file system now that the object store and RBD are in pretty good shape. That will mean both core fs/mds stability and features as well as integration efforts (NFS/CIFS/Hadoop). 'Ready' is in the eye of the beholder. There are a few people using the fs successfully in production, but not too many. sage > > And if there's a page documenting this already, I apologize...and > would appreciate a link :) > > t. > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > > -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
