Suppose we have a multi-level index file system, and this file system has $512$ Bytes blocks, inodes with $3$ direct, $1$ single-indirect, $2$ double-indirect, and $1$ triple-indirect pointer, and $64$-bit block identifiers.

At a minimum size, how large does a file need to be before the relevant inode requires the first single-indirect block number be used?

$1536$ Bytes
$1537$ Bytes
$512$ Bytes
$1500$ Bytes

The question is taken from Stanford.

$3 \ast 512 + 1,$ or $1,537$ bytes.

Why 1 Byte is added to it at the last

coz in 1536 we can use direct and it is written in question that

At a minimum size, HOW LARGE DOES A FILE NEED TO BE BEFORE THE RELEVANT INODE REQUIRES THE FIRST SINGLE-INDIRECT BLOCK NUMBER BE USED?

:- we add 1 for first single indirect block.
