NanoPi M4V2
I use for 4x SATA HAT for NanoPi M4 disks, raid created through raid management.
Now I turned on the server, and the raid was displayed, only raid status clean, degraded, and in the raid only 1 disk.

Ok, is that drive /dev/sdc visible in storage -> disks
You have to activate your inactive RAID. You need to do that manually via CLI, OMV can't do that automatically for you.

Yes, but how his add to raid?

The following may or may not work,
Raid Management -> Select the Raid -> on the menu click recover, a dialog will come up hopefully displaying /dev/sdc -> select it, click OK and the raid should resync.

Activate it and your good, do not do anything else or you will surely loose your data. Use Google how to do that or look into the forum, e.g. RAID5 disappears when removing 1 HD.

Unfortunately it does not work, / dev / sdc is not displayed in the list. If I format / dev / sdc in the drive list, will it appear in the raid recovery list?

Pity I would rather do this from the GUI, follow @votdev link, ssh into omv and run those two commands.
@dvortsov by the way, do you have a backup?
Yes, i have a backup. And my Reid1 is working, there is access to data, the problem is that I can’t add a second disk to Raid.

If your RAID is still inactive like mentioned in the first post, then this is absolutely not possible.

In post No. 5, I wrote that I had a raid on the list, that it was active again, but only 1 disk out of 2 was active.
cat /proc/mdstat
but only 1 disk out of 2 was active.
I take it you tried that link and the two commands didn't work

Tried two commands. After first command:
root@AsProDent-NAS:~# mdadm --misc -v --stop /dev/md0
mdadm: Cannot get exclusive access to /dev/md0:Perhaps a running process, mounted filesystem or active volume group?
How I can find a running process?
Tried two commands. After first command:
Tried that command on a VM that's running OMV5 same result, try mdadm --stop /dev/md0

Got it againe:
