May I suggested an update for ext4.txt file?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



kernel 2.6.28.7
efs2prog: 1.41.4

File Documentation/filesystems/ext4.txt states:

...
    Or to configure an existing ext3 filesystem to support extents:

        # tune2fs -O extents /dev/hda1
....


To convert from ext2 (a very old filesystem :) ) to ext4, it's necessary
to add more options. I'm not sure which one made the trick.

tune2fs -O
has_journal,dir_index,filetype,extent,flex_bg,sparse_super,large_file,huge_file,uninit_bg,dir_nlink,extra_isize 

Also, /etc/filesystems does not contain an entry for
ext4. /etc/efs2prog.conf is ok.
