I'm having trouble getting a custom startup script to run at the proper time. I'm having to use gnop with my new Western Digital WD10EARS (1TB, 4K sector size) because it reports the standard 512 byte to the OS. I'm basing it on http://www.cod3r.com/2010/06/zfs-on-western-digital-ears-drives/ which also says that it needs to be run on each boot so that ZFS will use the .nop devices. So, I've created a custom startup script to automatically do this for me at the proper time (before zfs starts and auto-mounts). I'm having trouble getting it to work properly though. In services -r, it is listed before the zfs startup script, but in dmesg the gnop messages come after the zfs startup messages. Below is excerpts from services -r, dmesg, and the startup script in its entirety. EXCERPT FROM services -r /etc/rc.d/hostid_save /etc/rc.d/mdconfig /etc/rc.d/mountcritlocal /etc/rc.d/gnop /etc/rc.d/zfs /etc/rc.d/FILESYSTEMS /etc/rc.d/var /etc/rc.d/cleanvar EXCERPT FROM dmesg Trying to mount root from ufs:/dev/ad0s1a ZFS NOTICE: Prefetch is disabled by default if less than 4GB of RAM is present; to enable, add "vfs.zfs.prefetch_disable=0" to /boot/loader.conf.
