Dear Folks， I am planning a files systems project and CephFS is under serious consideration. But browsering on the web i found some negative comments on CephFS about stability and losing data. So i would like to learn more on the latest development about CephFS statbility, either a successful story or a failure Could you please speak out, if you have recently successfully deployed CephFS on production, and which version? any statbility issues with CephFS? thanks a lot, samuel huxiaoyu@horebdata.cn
