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? I can't give you the date yet, simply because its too early to judge how stable the new ZFS is. 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 [EMAIL PROTECTED] http://www.FreeBSD.org FreeBSD committer Am I Evil?

While I'd seconded update info a month ago, I think it is no more inappropriate. 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.

2008/11/21 Zaphod Beeblebrox [EMAIL PROTECTED]: Once no new bugs appear any more, and old one are fixed. That's a pretty cop-out answer. Considering the the version of ZFS in 7.x has significant issues and the ZFS patches havn't shown any propensity to affect non-ZFS systems when ZFS is not running or loaded, the benefit of importing the new code seems to outweigh any caution you might feel. I can understand an answer such as not in 7.1, but immediately after ... given the standards we apply to release branches ... but a vague when no bugs seem to appear applies much less to a system like ZFS (still in flux) than, say, the new USB stack. Pawel will probably not say no to any offers of help by people who would like to help port and maintain the FreeBSD-7 ZFS support.

After 7.1 is released, then perhaps ZFS and the other new code it requires can be moved into 7-STABLE? That is certainly the intention, but I trust that everyone will appreciate the need to watch and wait before dumping an enormous and potentially risky filesystem change into the laps of all 7-STABLE users.

As 8-CURRENT got ZFS version 13 with the last commit and this bug was fixed in opensolaris snv_98 which introduced ZFS version 13, chances are high that this bug is already solved in FreeBSD. Or are you already using 8-CURRENT?
