New drive not mounted after reboot

Hello,
I move my dietpi_userdata to new drive. I mount it in dietpi-drive-manage. Set move dietpi_userdata to that new drive. It move all my data and today morning when I wake up everything was OK. I reboot my miniPC and drive was not mounted. I rebot few times, disconnect two other usb drives but dietpi still cannot find that drive.

When I connect that drive once again to my laptop and open gparted I see state unknown, like it will be not formated, without any partition.

Regards.

can you share following three information

lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid
cat /etc/fstab
dmesg -l err,crit,alert,emerg

Hi, I have connected drive to my archlinux laptop because I think I will need to copy all data from dietpi-sync folder on second Seagate drive.

That sda is my Seagate backup drive and that sdb is my new drive for dietpi_userdata.

I will connect now to my dietpi miniPC.

OK, now on dietpi:

sdb doesn’t seems to contain any disk/partition information. Looks like empty.

Yes, but it was OK. I don’t know how it’s possible because I format it and move all dietpi_userdata there.

  1. Can You tell me if I format that drive again and set dietpi_userdata. Then copy all folders from dietpi-sync?
  2. How to format that drive from dietpi? Or switch it to my laptop?

Regards.

you can use drive manager to format HDD using ext4 and to move user data folder

which folder dietpi-sync is synchronizing?

I make partition and try dietpi-drive manager but it failed:

It’s repairing now:

Dietpi-sync is synchronizing dietpi_userdata.

@Joulinar I format and mount succesfully.
Now when I want in dietpi-drive-manager move dietpi_usedata there I see errors:

[ INFO ] DietPi-Set_userdata |  - From : 
[ INFO ] DietPi-Set_userdata |  - To   : /mnt/Skyhawk/dietpi_userdata
[ INFO ] DietPi-Set_userdata | Please wait...
[FAILED] DietPi-Set_userdata | Please provide a source () and target (/mnt/Skyhawk/dietpi_userdata) directory for input.
[FAILED] DietPi-Set_userdata | Exited with error

the drive has some corruption. You should try to get this fixed first before trying to move data.

Drive looks OK when I “check and repair”

Can You tell me how can I set dietpi_userdata there?

first things first.

format your drive using ext4, mount the drive somewhere, reboot your system and try to access the drive on CLI. If all this is working we could continue.

Yes, I do that now it looks everything works OK.
Just don’t have dietpi_userdata on system.

our preferred option is to use drive manager to move user data folder.

I know but now there’s no source and i have error.

you need the source drive mounted and working to move user data using drive manager.

On my source drive where I have dietpi_userdata before there’s nothing left. Just docker-data and empty mnt folders.

@Joulinar I connect that old drive but still cannot move dietpi_userdata because there’s no source? What can I do with that? Reinstall system or is there a way to set dietpi_userdata folder manually?

Ok, I mount in different name as I before mounting and now it looks like it see dietpi_userdata there:

lrwxrwxrwx  1 root   root     28 11-25 05:05 dietpi_userdata -> /mnt/skyhawk/dietpi_userdata
drwxrwxr-x  2 dietpi dietpi 4096 2020-08-06  ftp_client

drwxr-xr-x  4 dietpi dietpi 4096 09-16 19:52 Toshiba

but there’s no folder on that skyhawk drive:

dietpi@DietPi:~$ ls /mnt/skyhawk/
lost+found

How to copy data from backup drive [dietpi-sync - it syncs dietpi_userdata from old drive]?
Do I have to mkdir /mnt/skyhawk/dietpi_userdata or some symlink?

where is the original user data located? On which drive?

Can you share as well

ls -la /mnt
