Thanks for reporting above problem. > Is it a misuse case of resize? > Kernel return -EFBIG in this case(dev not big enouth), and btrfs-progs output corresponding standard error message for this return value: "File too large" This message is almost right for most case, but not for resize. > And I expected not the message "File too large" but different error message. > Good suggestion, I will change it to some accurate description.
