To be honest, I couldn't find good directions on how exactly to resize an array to be smaller so I put some bits and pieces together to do it. Guess I didn't understand everything beforehand because I didn't read anything about resizing the file system. I thought setting the "array-size" would take care of moving data before rebuilding onto the 6 disks. Since I haven't resized the XFS filesystem, any recommendations on what to do next? Think it's possible to recover any of the data? For what it's worth, I haven't done anything to the 2 disks that I was going to remove. Thanks for the help.

It has been running fine for about a year. File system is XFS.
