Hi Forum,
I'm very new to FreeBSD, but have fairly well knowledge about Linux and *nix. I recently setup a file server with FreeBSD 8.1, and trying use zfs RAIDZ for data storage. The setup include:
After setup, the zfs performance wasn't so good, so I'm trying tune it. From read, I know I should use native ahci driver by put
into /boot/loader.conf, so I did. But after that, System cannot boot up because of cannot mount root
I did some research and saw somebody mentioned this error and recreate zpool cache. But that looks like for using zfs for root which is not my case. My root, swap, /usr, /var, /tmp and /home was located on 100G hard disk without any zfs. And because this happened during startup, after I remove it from /boot/loader.conf and boot up machine again, there's no log for that error at all.
Any suggestion on how to use
?
Thanks
