Sure - but you've got to satisfy a whole heap of alignment and size considerations when changing sunit e.g. AGs must be stripe unit aligned and their size must be a whole multiple of the stripe unit. Hence any new value generally needs to be a multiple so that filesystem alignment remains valid. You might want to get a recent kernel, too, as it will tell more about the reason why the mount with the new sunit is failing (in dmesg).
