The -a 0 means you're only looking at the first AG, which given the
history of the filesystem has a fair chance to be full. To get the
summary for all AG do a
xfs_db -r -c 'freesp -s' /dev/vg0/lv0
No idea yet on what could cause your problem, sorry.

Did you remount it with that option as in mount -o remount or did you
completely unmount it and mount it again? Unfortunately none of the
xfs-specific mount options can be reset with remount yet, and it doesn't
return an error either (both are added to my todo list now)
