less (right now, it is about 10 MB). First, I am sorry for replying to my own
mail, but wanted to add info to be clearer on what the issue is as I have done
more investigation. I build another image with jffs2 and when
I do a df, I see what I expect to: # df Filesystem
Size Used Available Use% Mounted on /dev/mtdblock4
256.0M 11.9M 244.1M 5% / # That is, there is a total of 256MB in the
partition and the kernel et al know about it. When I do the same thing with ext2, it
shows as having around 10.4 M for the size. This is no doubt in how the
file is built. Is there a way to have a file be, let’s say, 10 mb
big, but within the ext2 file, have it know that it has 256Mb to use? I
have tried using the block size but that just balloons the size of the file,
which is not what I am looking for. Thanks for any help or explanations on how
to properly build the ext2 file (ext2 is so much quicker to mount and seems so
much more reliable that I would like to use it, if possible. |
