parted 2.3 successfully resizes (shrinks) an HFS+ volume. fsck_hfs on Mac OS X
10.6.8 automatically repaired invalid file count and free block count and
automounted it. Unmounting and manually rebuilding the catalog with fsck_hfs -r
finds additional problems which are reported to have been successfully repaired.
parted 2.3 will not resize a journaled HFS+ volume. It says:
"Error: The sector size stored in the journal is not 512 bytes. Parted only
supports 512 bytes length sectors."
The disk is an AF 512e disk. Mac OS X sees the sectors as 512 bytes. The VM
sees them as 512 bytes as well. I don't understand what the error is about.

HFS+ != journaled HFS+.
At least Apple considers them different filesystems. Their resize tool
considered HFS+ to be non-resizable, and will only resize journaled HFS+.
Parted 2.4 documentation doesn't mention journaled HFS+. The code however does.
But I'm unable to determine why I get the mentioned error.

I don't know.
