FYI the only way I could recover the partitions semi successfully was rebuilding the arrays identically and then use gpart to recover the partition info. This would last for anywhere between 1-5 hours before the array would get broken. The only thing that changed on both systems when things started acting up was the addition of the line to /etc/exports. What would be the most appropriate list to further get info on to the cause of this. My best guess is there is a glitch in the HPT374 controller or a bug in the FreeBSD driver.
