Re: [ts-7000] How to reduce SD card image size?

You need to use the utility fdisk.
Read the man page on it.

Hello!

I had a 1 GB image size of a SD card (Master SD card with 1001216
blocks) with Debian and several packages installed for a TS-7260. I
want to create a new SD cards with this image.

I have bought some 1 GB SD (same manufacturer as SD card image, but
with 964864 blocks), but this new SD cards have a quite different
size than the "Master SD card", so when I execute dd command I
obtain:

#dd if=image1GB.dd of=/dev/sdd bs=1M
947+0 Input registers
946+0 Output registers

Master image is bigger than SD card, so when I put it in the SBC and
start Linux there are a lot of bad inodes during e2fsck. Linux can
repair it and boot up, but when I reboot I have the same problem.

I have tried to reduce image size on destination SD card using same
method than in the Wiki article(
http://www.seiner.com/ts7000/index.php/Copying%20Boot%20SDCard ) but
reducing partition size instead of growing it.

No good results have been obtained due to superblock specified a
size bigger than physical SD size (they don't match).

On the other hand, I have tried to copy this image in a 2 GB SD
card, reduce sdd3 partition size less than 1 GB (900 MB), create a
image of this card and copy it in a 1 GB SD card. No good results
have been obtained, because image have 2 GB size although there are
1.1 GB free without partition.

I have tried to perform a "mke2fs" in sdd3, but all file system goes
to lost+found :-(

Had anybody this problem before? Can anybody put some light in this
darkness, please?

Thanks in advance for your collaboration!

Bye!
