Impossibile unmount sda2 from / #56

Open vzlgdu opened 6 years ago

vzlgdu commented 6 years ago

Hi, I'm using with success the first versio of RPI-Clone on a Raspberry with raspbian Linux rpi3mh 4.9.46-v7+ #1032 SMP Wed Aug 30 12:09:14 BST 2017 armv7l GNU/Linux and every synch work fine.

After installing V2 of RPI-Clone, and executing "sudo rpi-clone sda -v", I receive the following message:

Destination disk partition /dev/sda2 is mounted on /. The clone cannot proceed unless it is unmounted. Do you want to unmount /? (yes/no): yes umount: /: target is busy (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).) rpi-clone could not unmount /. Aborting!

The source and destination are the same...

Where is the problem?

Please help me.

Thanks

Guido

sudo rpi-clone sda -v

This command will clone to sda...

Destination disk partition /dev/sda2 is mounted on /.

... but sda is the disk that you booted from. In other words you are trying to clone sda to sda which is a bad idea. You need to either clone to a different disk or boot from a different disk,

That's not necessarily meaning that sherazan booted from sda. rpi-clone 2.0 is broken since many months, see issue #49. Fix is to roll back to last known working 1.x, see https://github.com/billw2/rpi-clone/issues/49#issuecomment-338959704

Same here, i roll back to 1.7.1 and all work fine. When you could fix the 2.x version?
