[SOLVED] Raid 5 filesystem missing

So i build a youyeetoo with openmediavault

4 disk in there

the raid was fully functioning and i copied all my diving movies on there ready for backup

suddenly i get write protection, and now i get that the share is no longer able to be opened

and if i go in the web i see the file system is missing

any help in how to recover?

here are some screenshots that might help

the disks i use

the file system

the multiple file system this was configred but gone, and it's impossible to select drives here

also perhaps good to know md0 seems to be inactive

/dev/md0:

Version : 1.2

Raid Level : raid5

Total Devices : 4

Persistence : Superblock is persistent

State : inactive

Working Devices : 4

Name : youyeetoo01:0 (local to host youyeetoo01)

UUID : e0fa45e9:bd57d5f9:dc915596:e02988d9

Events : 5801

Number Major Minor RaidDevice

- 259 3 - /dev/nvme2n1

- 259 2 - /dev/nvme1n1

- 259 0 - /dev/nvme0n1

- 259 1 - /dev/nvme3n1

so i got them active and mounted again via ssh

in short

sudo mdadm --stop /dev/md0

$ sudo mdadm --assemble --force --verbose /dev/md0

sudo cat /proc/mdstat

to check if active

sudo cat /etc/fstab

then the raid and filesystem are active

however the shares aren't accesable

what i can see is my file system is mounted

however my shared folders don't link up

creating a new file system also doesn't work

any ideas?

well, seems I'm doing a conversation with myself, but at least someone else can perhaps use this

the raid, filesystem and shares are all up and running

the missing solution where these commands

sudo omv-salt stage run prepare

sudo omv-salt stage run deploy
