I'd definitely keep good backups though. Just read the mailing lists, or for kicks run xfs-test on your server. Xfs-test doesn't do any direct disk access or anything like that - it is no different than running bazillions of cat's, mv's, rm's, cp's, etc. It most likely will panic your system if you try it on btrfs - on ext4 it will probably load the living daylights out of it but you should be fine. The issues with btrfs at this point are the ones that aren't so easy to spot, like race conditions, issues when you use more unusual configurations, and so on. Oh, and go ahead and try filling up your disk some time. If your kernel is recent enough it might not panic when you get down to a few GB left. I'm eager for the rise of btrfs - it IS the filesystem of the future. However, that cuts both ways right now. Rich
