SDA partitions created then not found -> abort about rpi-clone HOT 34 CLOSED

I run rpi-clone, it seems to work (it's long)

from rpi-clone.

done successfully ! The problem came from the SD card I guess

from rpi-clone.

Thanks for help and advices !

from rpi-clone.

PS: last successfull save was 19th january 2023

from rpi-clone.

I did'nt check logs before today, shame on me !

from rpi-clone.

Thank's for fixing or tell me what to do for

from rpi-clone.

Hi @Philtass, can you confirm that the devices exists with the command:
sudo fdisk -l

from rpi-clone.

Hi viniciuspaes !
sudo fdisk -l gives (at the end):
...
Disk /dev/sda: 29,8 GiB, 32010928128 bytes, 62521344 sectors
Disk model: Storage Device
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

from rpi-clone.

Looking the log you have the OS installed in the SD card (/dev/mmcblk0)
Then /dev/mmcblk0p1 is the boot partition and /dev/mmcblk0p2 is the OS.

You want to clone everything to the SDA (assuming external drive). The RPI clone is not recognizing the label for SDA.

The command you used to clone was:
sudo rpi-clone sda

Correct?

from rpi-clone.

Yes

from rpi-clone.

previously I used "sudo rpi-clone sda -U" with same result

from rpi-clone.

It is weird that even parted is not recognizing SDA.

Double check if the command output the partitions:
cat /proc/partitions

from rpi-clone.

$ cat /proc/partitions

Just googled and saw some issues with parted. It is possible to create the label manually in case of corrupted or unrecognized disk label.

Have you tried to format the external disk manually already, to see the results?

from rpi-clone.

Not for the moment. I'm not sure of parameters.

from rpi-clone.

I see sda1 should be a fat32 and sda2 an ext3 but I never used command line to format a disk. I don't want to make a mess.

from rpi-clone.

Coul'd you give the right commands ?

from rpi-clone.

Plug the external drive in your desktop computer. If using windows, try to format the drive and do some tests.

Then plug it again in the RPi and try the clone process. I did this way with my RPi 4 and worked in the first try.

Don't worry about creating the partitions, just check if the drive is working properly first.

from rpi-clone.

I use linux. Have you a command line to format..

from rpi-clone.

Sure, hang on.

from rpi-clone.

Ok try that

from rpi-clone.

To erase the external drive (double check if the external drive is mounted as /dev/sda)
sudo dd if=/dev/zero of=/dev/sda bs=16M

Using fdisk to create the partitions:
sudo fdisk /dev/sda

Don't worry with the filesystem yet, just try to run rpi-clone.

from rpi-clone.

ok done that:
Device Boot Start End Sectors Size Id Type
/dev/sda1 2048 526335 524288 256M c W95 FAT32 (LBA)
/dev/sda2 526336 62924799 62398464 29,8G 83 Linux

from rpi-clone.

Nice, test the rpi-clone now.

from rpi-clone.

bad news:
sudo rpi-clone sda

Ok to proceed with the clone? (yes/no): y

sorry for weird formated text

from rpi-clone.

The SD card you are trying to clone, what OS do you have installed?

It is possible to manually create the boot partition, and then you just rsync the second partition (sda2).

from rpi-clone.

It's a standard raspbian, for a domoticz server.

from rpi-clone.

on a RPI 3B

from rpi-clone.

I did'nt check logs before today, shame on me !

Why don't you create a small wrapper script which calls rpi-clone and sends a failure eMail to you if rpi-clone fails 😉

from rpi-clone.

Hi framps. Good idea !

from rpi-clone.

But first I'd like to fix rpi-clone. Any Idea ?

from rpi-clone.

Do you have another external drive available? So we can isolate the problem.

from rpi-clone.

I try with another SD card with only one partition. rpi-clone creates the 2 partitions and continues... for the moment
