Keep in mind that while it's versioned at 2.6.39, it's actually 3.0.16 under the hood. It's just that some userspace doesn't like having a kernel version that doesn't start with "2.6" >> Out of interest, have you done a performance benchmark with ASM using ASMlib >> on the same platform? > > Sorry, no.

Perhaps, but ASM would provide all the functionality you require, including snapshots and rollback, at the highest possible performance. Certainly a lot higher than both ZFS and btrfs. And it's fully certified and supported by Oracle. As an alternative, why not consider using Oracle VM on the machine and creating database VMs instead? You can then use the snapshot capability of Oracle VM while still running supported and certified filesystems inside each guest. (We should also probably take this discussion off-list, as it has drifted away from btrfs proper).
