I have implemented a 171TB CephFS using Infernalis recently (it is set so I can grow that to just under 2PB). I tried using Jewel, but it had grief, so I will wait on that. I am migrating data from a lustre filesystem and so far it seems ok. I have not put it into production yet, but will be testing/playing with it one I have the 50TB of data copied over to play with. That migration is slower than I prefer, but so far so good.

Any direct experience with CephFS? Thanks for the help!
