Expand data.img ?

[Vincent Cojot]

Hi all,

I am using 8.1r2 on a Lenovo Yoga 12 with Windows 10 on it (for BIOS updates, mostly). Things are working well but I had made the poor decision of creating a data.img that was only 16g in size.

In other words, under Windows (NTFS), I have a c:\android_8.1r2\data.img that is 16gb in size (it's sparse so it doesn't take up that amount of disk space).

Is there a way to expand that data.img.file to something bigger? I looked at the file but couldn't figure out what type of filesystem was on it.

Any ideas? I'f like to keep the data but expand the size of the img file to avoid running out of space too often.

Also, it seems that data.img only gets created if I select 'system as read-write' or is it only when installing onto an ntfs partition?

Btw, that latop upgraded just fine from 8.1r1 to 8.1r2. Thank you!

Vincent

File system is ext4. Use Linux resize2fs command to resize the file system after resizing the image file.

I could not even find a partition table in the img file. What format (if any) is the image file in? qcow2 images usually have a format type with virtual size and features. Or is that just an mkfile?

It's just ext4 raw format.

Exactly what I was looking for.

Many thanks,

There are tools that can unpack data.img file in windows.

Hi,

I'm using Linux mostly (even if this laptop dual boots) so after being made aware of the steps, it was a 1 minute task to expand data.img successfully.

For the record, I used this:

* Expand data.img:
Boot to debug mode, then

# mount -o remount,rw /mnt
# dd if=/dev/zero bs=1G count=8 >> /src/data.img
(append 8G space to /src/data.img)
# e2fsck -f /src/data.img
# resize2fs /src/data.img
