In several of the recent ZFS posts, multiple people have asked when this will be MFC'd to 7.x. This query has been studiously ignored as other chatter about whatever ZFS issue is discussed. So in a post with no other bug report or discussion content to distract us, when is it intended that ZFS be MFC'd to 7.x?

However, Pawel was on travel last weekend and week attending MeetBSD and the FreeBSD developer summit in the bay area, and hasn't been seen on stable@ since the 17th. I think it's likely not so much that anyone is being studiously ignored, it's that the person who can best answer he question hasn't been keeping up with the list for a bit.

Work is actively ongoing (if you follow -current) and now it's time to take out that old (or new) box and help debugging all possible scenarios on CURRENT before crying after the next kmap_too_small or panic. If I understand correctly, the issues arising with large de/allocations of memory in kernel space is a tricky buisiness which needs careful and thorough testing, tuning and thinking... Afaik, even solaris hasn't ironed out all the potential problems, e.g. if you read this article and the linked bugdatabase entries...: http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#Limiting_the_ARC_Cache So let's really rather help (if possible) with a -current install, or at least not take time with tedious requests :) Sincere regards to PJD and the whole development core team, as FreeBSD is really keeping up with the fast tech hype - but with style.

The amount of code changes is really huge. The ZFS functionality is also huge (which is good for the users, not so good for me) and I'm simply unable to test entire thing. While I was working on ZFSv13 port I started working on regression tests as well (you can find some in tools/regression/zfs/) so I could have more automated testing. Eventhough I implemented 2850 tests, it not even covers entire zpool(8) functionality. All in all. People are using ZFS in production, but not only them won't be happy to lose their data, so I'm not going to MFC ZFS until I'm convinced the new one is at least not worse than the old one. To speed up this process everyone is very welcome to try ZFS on HEAD and report results (both bad and good). The current plan is to have new ZFS in 7.2. For this to happen, some other changes have to be MFCed too, like *at() syscalls, etc. I hope this helps to understand what's going on. -- Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
