Hi, FreeBSD 8.1 r218475. I have a raidz2 with 6x2TB devices; 3x2tb HDD and 3 stripes of 2x1TB HDD. I have ufs / on USB flash. After boot0 starts and the USB boots it displays Drive C: is disk0 etc. for each drive. Then I can hear all the drives making noises. Sounds like the devices are being tasted, with the spinning char. This goes on for sometime. Often the machine hangs solid and I have to reset. It can take 3 or 4 attempts before the OS boots. I can tell it's hung by pressing the caps lock key. If the capslock light doesn't work I hit reset and cross my fingers. It's been like this for as long as I can remember (i.e. many different source trees). How can I fix this? I thought it might be a BIOS fault and not FBSD, so I was considering a new motherboard. However, if I have ufs / can't I stop all this tasting/zfs nonsense at boot and let the kernel do it all later and therefore not susceptible to any possible BIOS faults? I tried to rebuild with: LOADER_ZFS_SUPPORT=no in make.conf, but it seems to make no difference. Any ideas?

You say you have a raidz2 so I take it your server was working before ? The question I'm asking here is: before what ? Did you upgrade from 8.0 to 8.1 ? It may not be the best piece of advice you'll receive but I would try the following: 1/ a verbose boot, you never know. 2/ unplug a disk, try to boot, rinse/repeat until it works, to identify a potentially *very* faulty drive.
According to Mark Powell:> etc. for each drive. Then I can hear all the drives making noises. > Sounds like the devices are being tasted, with the spinning char. > This goes on for sometime. Often the machine hangs solid and I haveThe controller has just been resetted by the driver and is now proceeding to spin the drives up (or just reset each of them) to make sure they are ready. Some controllers do that before loading the kernel, some later would be my guess.> LOADER_ZFS_SUPPORT=noI do not think it is ZFS related at all. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.net In memoriam to Ondine, our 2nd child: http://ondine.keltia.net/

Can you take a picture of where it hangs? (you will have to host it somewhere though, as the list will reject non text attachments). I suspect it's in the loader and quite possibly it's your BIOS that is at fault, or at the very least there is a nasty interaction with it. Is there an update for the BIOS?
