No it isn't.

- Triebwerk

Ok, never seen this before, so lets's try something
mdadm --assemble /dev/md127 /dev/sdc
after that does it appear under Raid management
-
mdadm --assemble /dev/md127 /dev/sdc
root@openmediavault:~# mdadm --assemble /dev/md127 /dev/sdc
mdadm: /dev/md127 has been started with 1 drive (out of 2).
root@openmediavault:~#Now there is a raid shown, but just with one singe device (sdc) and the name of the drive is /dev/md127.

Now there is a raid shown, but just with one singe device (sdc) and the name of the drive is /dev/md127.
Does it show as clean/degraded
-
Yes it does.
-
OK, select the raid by just clicking on it, then on the menu click recover, a dialog box will appear if /dev/sdb is shown select it (a tick will appear in the check box) click ok.
-
Now it got 2 devices (sdb + sdc) and show a rising percentige of recovering.
It' seems to work now.

when it's finished run omv-mkconf mdadm don't run it before.
-
Okay. If the remaining time is shown correct it will take nearly 3 hours. I will run it and tomorrow morning I will run the comand you gave me and I will report it here.
Many, many thanks for your help. I'm sure that I won't make it to this point without your outstanding help.

Back agin. Now both drives are recognized but it seems the data of the drives are gone.
How can I get back the data ?

The data is there the shares are missing in OMV that will display the data, use WinSCP or Filexilla if you have Windows and look in /srv
-
I used WinSCP and the only content in srv is a ftp folder with a file called welcome.msg nothing else. I don't know why there is a ftp folder, because I never used ftp. Not in the previous version (OMV 2.x) and also not in the actual (OMV 4.x)

Ah! You had a previous running OMV2 and as @votdev pointed out the norm to upgrade was to backup, wipe the drives and recreate the array in OMV4.
I started using OMV from v3 the upgrade to OMV4 was straightforward, I am wondering if the mount point in OMV2 was in a different folder, you need some help from others @macom @ryecoaaron thanks.
-
Before /srv/ filesystems were mounted in /media/

Thanks @macom

The /media folder is empty.
I get the fear that the data will be lost.
Anyway, it's a repeating but I'm really appreciate you guys guided me to this point. These board can be really proud of to have guys like you in here.

The only way that could happen is if the drives were wiped all you have done (hopefully) is reassemble the raid.
-
I've tried to reassemble it, but it seems to fail. That is what's scare me the most. I tried several methods to restore the data and none of the ways worked well.
All I've tried to update OMV in normal ways failed. I thought when I connect one of the raid drives to an linux machine (Debian 10 in my case) I'll be able to access the data stored on, but it doesn't work either. That's sets me back and let me think about a new/other NAS solution.

You can't update/upgrade OMV unless one is moving from OMV3 to OMV4, there is no upgrade path from OMV2 to OMV4 or even to 5, to move to either of those versions you need to backup, then wipe the drives within OMV's new install, create the shares and move the data back.
What makes no sense is that the raid according to your posts 55 and 56 the raid has successfully reassembled, simply reassembling would not wipe the data, checking using WinSCP or Filezilla you are looking inside the raid mount point (sorry got to ask).
-
I'm not sure what you mean. Both drives were recognized and shown with it's full size. Maybe I'm wrong but it wouldn't be the case when it were unmounted (screenshot).
Administrative language is german but it doesn't really matter for the screenshot.
