THE FOLLOWING FILE SYSTEMS HAD AN UNEXPECTED INCONSISTENCY:
        /dev/vinum/rd4 (/var/d4), /dev/vinum/rd3 (/var/d3), /dev/rccd0c (/var/d0)

ccd0c was not configured via ccdconfig at the time fsck was run.
With the unconfigured vinum everything seems to be OK.

How-To-Repeat: 
run fsck on an uncofigured ccd device.
