What kind of machine do you have? i.e. what processor? The driver is only in the GENERIC kernel on the amd64 architecture, since that is the only architecture it has been tested on. Can you send the output of 'dmesg' and 'pciconf -lv'?

It is only included in GENERIC on amd64, since that is the only architecture that I know of that it has been tested on. It may work on i386, if anyone would like to try it out. There are known endian issues, so testing on a big-endian platform (like powerpc) won't work. If you'd like to help fix the endian issues, let me know. Integrated RAID support is not included in this version of the driver, but LSI has almost completed their version of the driver that does include IR support. That will hopefully be going into -current in the next few weeks. There are lots of changes in their version of the driver, particularly in the probe code. There are also a couple of othere issues with the driver that I am planning to fix in -current today and merge back into stable/8 in a few days. In particular I have fixes for these issues: - I/O locks up when you run out of S/G chain frames. - The device queue is not frozen on errors. - For some firmware revisions, the firmware will not return all outstanding commands for a device when the device goes away. Cleanup logic is needed. Let me know if you run into any issues.

Please be aware of a performance issue affecting certain models of WD RE4 disks. Specifics are still sketchy, but you should read the thread "immense delayed write to file system (ZFS and UFS2), performance issues" in full to get an idea of the problem: http://lists.freebsd.org/pipermail/freebsd-stable/2010-January/thread.html#54185 There's confirmation of the problem here, with the statement that WD gave at least one person a firmware image that fixed the problem: http://lists.freebsd.org/pipermail/freebsd-stable/2010-January/054489.html Buyer beware. :-) And remember, it's not an issue with the brand/vendor, just certain models. Caviar Black drives don't appear affected (and don't let the TLER stuff make you lose focus), which is one reason why I advocate them. -- | 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.

The best stress test I have found has been to just do a single sequential write stream with ZFS. i.e.: cd /path/to/zfs/pool dd if=/dev/zero of=foo bs=1M Just let it run for a long period of time and see what happens. What model controller do you have, and what firmware do you have on it? I have run into some bugs with the LSI 2.0 firmware, notably that you'll get IOC Busy errors as well as some bogus invalid LBA errors with SATA disks. (I'm guessing it wouldn't happen with SAS disks.) The 8.0 firmware is better, but the version for the 9211-8i is not able to recognize large numbers (more than 20) drives. (I reported that to LSI and they supplied a fix.)

No -- /dev/urandom maybe, but not /dev/random. /dev/urandom will also induce significantly higher CPU load than /dev/zero will. Don't forget that ZFS is a processor-centric (read: no offloading) system. I tend to try different block sizes (starting at bs=8k and working up to bs=256k) for sequential benchmarks. The "sweet spot" on most disks I've found is 64k.

It walks through various block sizes and is very long running. It can probably tickle lots of stuff.

That'll be up to LSI most likely. If it has the mpt2 interface, then I'm sure they'll support it through the mps driver. If it has the MegaRAID interface, then the mfi driver would need to be modified.
