Difference between bbox mke2fs and standard one (dumpe2fs comparison):

|

|
2009-10-22 15:42:17 +05:30

[upd: inode size has been fixed since then]
|

2009-10-21 17:31:25 +05:30
|
|
|
Two significant differences:
|
|
|
|
|
- standard mke2fs has resize_inode feature and thus has reserved GDT blocks,
|
|
|
|
|
which decreases free blocks;
|
|
|
|
|
- inode size: 128/256 (since 679807k is >0.5G, standard mke2fs uses "big" inodes)
|
|
|
|
|
this affects inode table in block groups
