[ale] Directories swapping contents!?!?!?

[W. Keith Miller]

Certainly an interesting problem.  Without attaching significance, I
noted that the partition types on the RAID drives were "83" not "fd". 
People on the list are correct that causes could range from PEBKAC to
file system meta-data issues.   It would be interesting to know how long
it took to recognize this problem. Did the directories/content switch at
once or "bleed" over a period of time?
