Here is my fstab
/dev/sd0s1b                     none            swap    sw 0 0
/dev/sd0a                       /               ufs     rw 1 1
/dev/sd0s1g                     /spare          ufs     rw 1 2
/dev/sd0s1f                     /usr            ufs     rw 1 2
/dev/sd0s1e                     /var            ufs     rw 1 2
/dev/sd1a                       /bg             ufs     rw 1 2
/dev/sd1b                       /bg1            ufs     rw 1 2
proc                            /proc           procfs  rw 0 0


With the above setup it took 1 minute and 5 seconds to fsck my two disks.

The need for higher speed 8) Okay, I meant 5400 rpm.

I hope that you have multiple scsi controllers 8) I just have one 
adaptec 2940 which is adequate for my 2 scsi disks ...
