Hi,<br>
<br>
I came across this<br>
<br>
$sudo dumpe2fs /dev/sda1<br>
<br>
4KB Block Size<br>
Group 0: (Blocks 0-32767)<br>
Primary superblock at 0, Group descriptors at 1-1<br>
<br>
1KB Block Size<br>
Group 0: (Blocks 1-8192)<br>
Primary superblock at 1, Group descriptors at 2-2<br>
<br>
Why does first block start from 0 in the 4KB block size partition and<br>
1 in 1KB block size partition ?<br></blockquote><div><br>Let's say superblock is always written at a fixed offset of 1024 (they have to because e2fsck has to find it) in the filesystem. What would be the block numbers with block sizes 1k and 4k ?<br>
