Shrink is partially supported -- if there's free space at the end of the filesystem, you can reduce the filesystem by the size of that extent. To make shrink more useful, the codebase will need to gain the ability to offline an entire AG, move metadata structures, and perform free space defragmentation. Alpha-quality implementations of those last two things are in my development tree, but the entire thing is on ice while we try to merge the online repair code. --D > roy
