Hi,
I came across this
$sudo dumpe2fs /dev/sda1
4KB Block Size
Group 0: (Blocks 0-32767)
Primary superblock at 0, Group descriptors at 1-1
1KB Block Size
Group 0: (Blocks 1-8192)
Primary superblock at 1, Group descriptors at 2-2
Why does first block start from 0 in the 4KB block size partition and
1 in 1KB block size partition ?
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 ?
Regards.
