This problem is evident on 8.0-RELEASE and 8.1-PRERELEASE.

This can be done with an enabled write cache for a RAID controller and inopportune powercycling. Any attempt to access the pool in that system will cause checksum mismatch errors to be reported in /var/log/messages. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
