Check if this works for your case: echo > myfile P.S. not the "solution", but may help in case you fill the disk by accident, and need to make some room before a remount cycle. P.S.2. this could help also when your disk is already 100% full, without enough space for deleting files -not enough space for new inodes- (I tested that case on ZFS NAS with no left space at all, and worked).
