own as 256MB), but the critical part is running a 64-bit
kernel. ZFS does a lot of kernel malloc/free operations, and address space
fragmentation on a 32-bit system will eventually cause a panic when ZFS
can't malloc a contiguous 128k chunk.
ou really want an exportable /tmp, just live with the fact that you'll
get ESTALE errors on all clients when you reboot the server. Maybe giving
the root inode a constant generation number is all that's needed, since I
suppose most clients that have mounted the server don't actual
py with the result. I've
never done it completely remotely, but if you do a trial run or two on a
local machine or VM, you should be able to it confidently remotely.

I'm running 7-STABLE as of Feb 26 or so. Commit r187466 on Jan 20 bumped up
kmem_size_max on amd64 to 3.6GB:
http://svn.freebs
ou've probably reduced kmem_size from the default. I don't set anything on
my 6 GB amd64 system, and I get:
$ sysctl vm.kmem_size vm.kmem_size_max
vm.kmem_size: 2061496320
vm.kmem_size_max: 3865468109
I assume your 16GB system would default to even larger numbers. What values
do you get w
covery tools in case your non-UFS root has problems of any sort, and /boot
always points to what you (and makefiles) think it should. If you have root
on mirrored disks, you can gmirror /.boot too. Works great for ZFS; should
work for HAMMER.

malloc silently rounds zero-size mallocs to 1. Ideally malloc would
return unique pointers to blocks of memory set to MPROT_NONE via
