  Respectfully, go bother the LVM, jfs, ext, afs, and all the other 
file
system people.  You have zero chance of getting them on board to support
online file system shrinking without any guarantee of scratch space.
My advice is that you don't tell them you also want them to resize while
the md volume is being resized, and also don't tell them that the array
might be degraded.

I didn't bring up nor argued the filesystem online resize issue, you  
did.  Why does the filesystem have to be online during the reshape or  
the shrink?  People shrink filesystems and partitions while offline  
everyday, and the sun still rises.  Filesystem support for reshaping  
(not resizing) should be a non-issue.  Resizing shrink exists today.

Not for xfs.
