I still haven’t gotten around to cleaning up this space, but a quick one liner to let you see all your folder affinities in one place, compliments of the find command and cvaffinity.

From the terminal, run the following:

find /Volumes/SANNAME -type d -maxdepth 1 -exec cvaffinity -l '{}' \;

And now you have a nice list showing you the affinity set to each folder, up to 1 level deep, on the volume SANNAME. If you want to go more granular, increase maxdepth to 2,3,etc.

And if you want to change an affinity on a folder after it has files in it, sometimes the files will not be moved to the new affinity, but you can let snfsdefrag do that for you (note: this can negatively impact your performance while the command is running, use the affinity name as labeled in your volume .cfg file, have backups, etc. etc.):

snfsdefrag -vr -k Affinity -m 0 /Volumes/SANNAME/foldertochange
