resize_inode

[seth bollinger]

Hello All,

I'm trying to create a small SD card image that I can quickly dd to card 
and then do an online resize as a post process step to take advantage of 
the entire space of the card.  Similar to how the raspbian image works.  
Unfortunately genext2fs doesn't seem to set this flag (and reserve the 
required resources), so the online resize fails.  I tried using tune2fs, 
as it looked like there was some interest in adding support, but it 
looks like it never happened.  Has anyone else run into this issue?  Is 
there a solution?

resize2fs 1.42.1 (17-Feb-2012)
Filesystem at /dev/mmcblk0p2 is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 15
resize2fs: Filesystem does not support online resizing

| Setting filesystem feature 'resize_inode' not supported.
| tune2fs 1.42.1 (17-Feb-2012)

Thanks,

Seth

genext2fs is a bit limited, this is just one example of how.

Could you not just do an offline resize of the filesystem though? Why does it 
need to be mounted?

Cheers,
Paul
