Status

Thanks for the replies, having some stats would be good. Its also good to know that the 4GB limit is only a problem for an edge case.

I do have to raise the issue over BTRFS, The fact that it is included in an Oracle produce does not make it stable - it is not itself an Oracle solution. If you go to the BTRFS site ( btrfs.wiki.kernel.org ) it makes the status very clear

Is btrfs stable? Short answer: No, it's still considered experimental. Long answer: Nobody is going to magically stick a label on the btrfs code and say "yes, this is now stable and bug-free". Different people have different concepts of stability: a home user who wants to keep their ripped CDs on it will have a different requirement for stability than a large financial institution running their trading system on it. If you are concerned about stability in commercial production use, you should test btrfs on a testbed system under production workloads to see if it will do what you want of it. In any case, you should join the mailing list (and hang out in IRC) and read through problem reports and follow them to their conclusion to give yourself a good idea of the types of issues that come up, and the degree to which they can be dealt with. Whatever you do, we recommend keeping good, tested, off-system (and off-site) backups. Pragmatic answer: (2012-12-19) Many of the developers and testers run btrfs as their primary filesystem for day-to-day usage, or with various forms of "real" data. With reliable hardware and up-to-date kernels, we see very few unrecoverable problems showing up. As always, keep backups, test them, and be prepared to use them.

Oracle's own web site has worse to say but this maybe dated as it also links across to the BTRFS site for new information.


As such it would be nice to know the exact version of the code base that ships with each ReadyNAS OS release so that it will be possible to tell the status of the underlying file system.

Thanks.
