zyxel 325v2 migration fail

Ok, i have both disks in, the new 4 TB-Disk is in Slot 1 and the old 3 TB-Disk is in slot 2.
Next i checked the Name and if there was a MD-Device.~ # cat /proc/partitions major minor #blocks name 7 0 143360 loop0 8 0 3907018584 sda 8 1 498688 sda1 8 2 3906518016 sda2 31 0 1024 mtdblock0 8 16 2930266584 sdb 8 17 498688 sdb1 8 18 2929766400 sdb2 31 1 512 mtdblock1 31 2 512 mtdblock2 31 3 512 mtdblock3 31 4 10240 mtdblock4 31 5 10240 mtdblock5 31 6 48896 mtdblock6 31 7 10240 mtdblock7 31 8 48896 mtdblock8 9 0 3906516992 md0 9 1 2929765240 md1 ~ # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] md1 : active raid1 sdb2[0] 2929765240 blocks super 1.2 [2/1] [U_] md0 : active linear sda2[0] 3906516992 blocks super 1.2 0k rounding unused devices: <none>
So the old disk is md1. The md-Device is stopped:~ # mdadm --stop /dev/md1 mdadm: stopped /dev/md1
Next i want to build the loop-Device on the old disk!?!:~ # losetup -o 1048576 /dev/loop1 /dev/<b>sdb2</b>
When i enter this Code, nothing happens. I do not get any info, no errors, i can just keep on entering commands. So i entered the command to mount the loopdevice:~ # losetup -o 1048576 /dev/loop1 /dev/sdb2 ~ # mkdir /mnt/mountpointmount -o ro /dev/loop1 /mnt/mountpoint mkdir: invalid option -- 'o' BusyBox v1.17.2 (2017-06-23 10:40:08 CST) multi-call binary. Usage: mkdir [OPTIONS] DIRECTORY...
Am i using the wrong comment with:~ # losetup -o 1048576 /dev/loop1 /dev/sdb2
And just for my understanding: I want to create the loopdevice on the old device (with all my data on it) and then find the mountpoint of the NEW device md0 with:cat /proc/mounts | grep /dev/md<b>0</b>
In the last step, when i enter a share, will this copy all data from the old drive?
And is it "admin" or could it be something else on my device?
Again, i don't know how to thank you enough!

mkdir /mnt/mountpointmount -o ro /dev/loop1 /mnt/mountpoint mkdir: invalid option -- 'o'
It's this marvelous forumsoftware which glued the lines together. I edited my post.And just for my understanding: I want to create the loopdevice on the old device (with all my data on it) and then find the mountpoint of the NEW device md0 with:Yes. grep searches for patterns, so without that 0 it will show both.In the last step, when i enter a share, will this copy all data from the old drive?Yes. 'cp -a' is a sort of clone command. The 'v' makes it verbose, so you can see all files copied. You can use any directory on your new disk, I used admin because I know that exists.
And is it "admin" or could it be something else on my device?

So this is the output.
Do these following commands do anything? Should i wait some time before executing the next command?~ # losetup -o 1048576 /dev/loop1 /dev/sdb2 ~ # mkdir /mnt/mountpoint ~ # mount -o ro /dev/loop1 /mnt/mountpoint
I get no output for that.

/i-data/d765169d/admin # cp -av /mnt/mountpoint/*
<pre class="CodeBlock"><code>cp -av /mnt/mountpoint/* .You missed the subtile dot at the end. That means 'copy to current directory. Now the last directory on the source is used for that. (And fails, as, for safety, the device is mounted readonly.I get no output for that.That is normal in Linux world. A succeeded command doesn't give any output, unless the output is a desired result.

Ok, i executed all the commands and it sounds like the HDDs are working.
I should get some info in the Command-Window at some point?
Will it tell me, when it is finished?

? 'cp -av' is supposed to list all files it's copying. When done, you will get back on the prompt.Meanwhile you should be able to see your files appearing in the admin share.0

I did not get any info about the files being copied, but the Disk got fuller and fuller in the WEB-UI. I have all the data back, tomorrow i am picking up a external HDD to have a Backup!
Thank you soo much for your help!!!!
