[3320] | 1 | Difference between bbox mke2fs and standard one (dumpe2fs comparison):
|
---|
| 2 |
|
---|
| 3 | [upd: inode size has been fixed since then]
|
---|
| 4 |
|
---|
| 5 | Two significant differences:
|
---|
| 6 | - standard mke2fs has resize_inode feature and thus has reserved GDT blocks,
|
---|
| 7 | which decreases free blocks;
|
---|
| 8 | - inode size: 128/256 (since 679807k is >0.5G, standard mke2fs uses "big" inodes)
|
---|
| 9 | this affects inode table in block groups
