I have found the cause of my troubles. Using FixIt I was able today to 
use my ad8 with gpart and newfs it without errors. I also found out that

zpool scrub pool was waiting for an uninterruptible disk wait. That made

me remember I used to have troubles before in this hardware setting.

The problem lies in a flaw in my MB. I have one ATA disk attached as 
master and an ATAPI dvd drive (slave) on ATA channel 0 plus four SATA2 
drives (ATA channel 4,5,6,7 master). Somehow this does not work OK. 
Without the ATA drive on channel 0 (an older model) my four SATA2 drives

work perfectly. I suspect some kind of interrupt issue.

Problem: FreeBSD is installed on my ATA drive on channel 0. I tried to 
do a minimal install on drive ad8 today to dump/restore the system over 
and get rid of that lousy ATA drive. Bad luck. Sysinstall can't find 
/dev/ad8s1b so it can't complete the creation of the filesystems. And 
thus I can't do a minimal install on this SATA2 drive.

Any ideas how I can overcome this issue?

Bit of a long shot, but have you tried enabling AHCI mode for the sata
drives in the bios and setting ahci_load="YES" in /boot/loader.conf
assuming your the board supports it.
