The recently acquired parts for the server were assembled two nights ago, and FreeBSD was installed last night.
I’m thinking of crowd sourcing the tuning of the ZFS monster I’m creating. Interested in watching/helping? See the FreeBSD Forums for details.
Here’s the dmesg output for future reference.
You will notice that (see line 154-157) one of the drives is running at only 150.000MB/s, as opposed to the other drive (lines 143-146), which is running at 300.000MB/s. The reason: the SATA cable is plugged into a lower speed SATA port. Changing the cable to another, faster port, bumped that HDD up to 300MB/s.
