Subject: [PATCH 3/8] mke2fs: disable resize_inode feature if 64bit feature is
|
|
|
ec15cf |
enabled
|
|
|
ec15cf |
|
|
|
ec15cf |
Since auto_64-bit_support is on by default, resize_inode feature will
|
|
|
ec15cf |
be disabled when creating a >16T ext4 according to mke2fs.conf(5).
|
|
|
ec15cf |
|
|
|
ec15cf |
This should also be done when making ext4 with "-O 64bit" to enable
|
|
|
ec15cf |
64bit feature explicitly. Otherwise online resize to enlarge a
|
|
|
ec15cf |
over-16T fs to larger would fail.
|

|
|
ec15cf |
With this fix resize2fs could do the online enlarge correctly.
