#270 zesty mis-calculates destination partition size.

[William Smith]

zesty 16-11-14.

cloning Raspberry Pi 3b

on raspberry pi, install distribution microSD as Raspbian

on server, clone using device to device using an identical microSD as target using beginner mode (both SDs are in USB slots.)

/dev/sdb7 (target) is one count larger than /dev/sda7 (source), thus expert mode -icde -k1 must be used.

/dev/sdb7 was moments earlier copied from partition table on /dev/sda.

this error is not produced on lower numbered partitions...perhaps size related.

I think I may have seen this on earlier versions as well.

Could you please show us the partition table by running:
sfdisk -d /dev/sdb
Thanks.

sorry, i didn't get an email with your response.

"/dev/sdb7 (target) is one count larger than /dev/sda7 (source), thus expert mode -icde -k1 must be used." -> Not really, you can use the the same partition table from souce without using opitons "-icds -k1" because source is smaller disk is than destination one.
The mechanism to calculate destination partition size for logical device is broken in this case, that's true. It's complicated so "-k1" option won't work, especially for logical drives.

not so - read it again (or maybe I don't understand your response).

beginner mode - duplicate device to devce - source partition is being used, but copy fails with an incorrect sector count.

source and target devices are the same size - exactly. same brand/model nand.

...so is it a bug you will fix, or continue using work around?

Even for the same brand, same model, it's still likely that the size is only 1 byte different. Therefore could you please run:
parted -s /dev/sda unit s print
parted -s /dev/sdb unit s print
Then post the results of these two commands?
Thanks.
