RELENG_7 uses ZFS v13, RELENG_8 uses ZFS v18. RELENG_7 and RELENG_8 both, more or less, behave the same way with regards to ZFS. Both panic on kmem exhaustion. No one has answered my question as far as what's needed to stabilise ZFS on either 7.x or 8.x. The people who need to answer the question are those who are familiar with the code. Specifically: Kip Macy, Pawel Jakub Dawidek, and anyone else who knows the internals. Everyone else in the user community is simply guessing + going crazy trying to figure out a solution. As much as I appreciate all the work that has been done to bring ZFS to FreeBSD -- and I do mean that! -- we need answers at this point. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
