Hi.
http://people.freebsd.org/~pjd/patches/zfs_20080727.patch.bz2
The patch above contains the most recent ZFS version that could be found in OpenSolaris as of today. Apart for large amount of new functionality, I belive there are many stability (and also performance) improvements compared to the version from the base system.
Check out OpenSolaris website to find out the differences between base system version and patch version.
Please test, test, test. If I get enough positive feedback, I may be able to squeeze it into 7.1-RELEASE, but this might be hard.
I currently don't have high-end (4 CPU+) AMD64 machines to test, but with 1 CPU i386 virtual machine in VMWare, with 1 GB of memory, kmem_size=kmem_size_max=512M and no other tuning, with latest zpool format (11) it took about 15 minutes to get a "kmem_map too small" panic on a mixed load (buildkernel + blogbench + bonnie++).
I've then tried the same load on the "real" hardware, 2 CPU, 2 GB memory, kmem_size=kmem_size_max=512M, and no other tuning, with the older zpool format (6) i get the same panic, though it takes about twice as long to happen.
Have you tried tuning arc_max and/or monitoring vmstat -m to see what is happening? What does arc_max get auto-tuned to at the moment (ie. without manually specifying)?
One of the things I recall reading that arc_max is more like a guide, as some ZFS threads can exceed the max whilst other thread(s) go around cleaning up and freeing memory once the limit is hit.
Maybe some better smarts are needed in auto-tuning arc_max so that it leaves more of a buffer zone than it does at the moment...?
