Guys, please don't start a flamewar. And lhmwzy we discussed this on the DFly lists. It's really up to them... that is, a programmer who has an interest, inclination, and time. It isn't really fair to try to push it. You're right. I personally believe that the FreeBSD community as a whole should focus on ZFS for now.

Though I don't have too much experience about filesystems, I personally would be interested in this since it would be a pretty good way to learn it. The biggest problem for me right now is the lack of time. I'm a full-time student right now :( If you have some experience in C and time, you can try to do some work, then announce to others. Maybe a developer will volunteer and act as a mentor. As far as I know many FreeBSD developers started that way. I remember PJD 7 years ago telling me that he's learning how to use FBSD, and look at him now :) I don't think I don't know how to is a good excuse. -- Best regards, Derekmailto:[EMAIL PROTECTED] -- Will the information superhighway have any rest stops? ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

This has happened in the past for some key features. Like I said, it all depends on how much it matters to you. Another big consideration, is is 'HAMMER' sufficiently 'finished' to be worth trying this yet? Anybody attempting a port is going to have enough to worry about with the VFS/VM semantics differences, locking differences etc between the two different kernels. Having to worry about following a moving target as well would add unneeded difficulty. To be honest, I've not looked at the state of HAMMER. Is it still under active development or is it in a state where you could easily work from a snapshot of the source for months and not have to worry about getting too far out of sync, or be in need of functionality or bug fixes? That was one of the things that made the ZFS port possible. It was possible to take a known-good, complete, working snapshot as a base and focus on getting it working in the FreeBSD kernel. It wasn't necessary to wonder (that much) if the bug you're currently fighting is a porting bug or an underlying ZFS bug. Of course, there's a lot more to it than that, but having a solid starting point is very important. -- Peter Wemm - [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; KI6FJV All of this is for nothing if we don't go to the stars - JMS/B5 If Java had true garbage collection, most programs would delete themselves upon execution. -- Robert Sewell ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

This has happened in the past for some key features. Like I said, it all depends on how much it matters to you. HAMMER seems good, but at this time, it is more important to finish ZFS integration in to FreeBSD. Fixing all known issues, more testing, wider audience and make it production ready. Not because ZFS is better, may be is worse - it does not metter. I think it is important to have one successful port finished than two filesystems in non-production state. FreeBSD is currently lag behind other operating systems in supported filesystems. UFS2 is insufficient for todays storage requirements. Once we have ZFS production ready, we can talk about another filesystems. I can't do any programming to port whatever filesystem, nor write patches. All I can do is testing and reporting - and I am doing it. I have some stresstests of ZFS. Currently I have one ZFS mount with 56 snapshots taken during heavy tasks like coping or removing large number of small files (mainly cp -R /usr/ports /tank/test/$i in loops plus taring / untaring tasks), some large files creation with dd on background etc. All is running fine on FreeBSD 7.0 amd64 with 4GB RAM and some kernel tunning. vm.kmem_size=1024M vm.kmem_size_max=1024M kern.maxvnodes=40 vfs.zfs.prefetch_disable=1 vfs.zfs.arc_min=16M vfs.zfs.arc_max=64M There are 53202511 inodes on ZFS partition.
