It was raid5 with 4 disks ( 3tb-3tb-1tb-1tb) But it looks like 3 of those were broken.
I did a raid recovery to a company and they repaired the disks and i was be able to get the data.
thanks for your time.

i have a raid which is inactive and i cant start it.
The Story: i noticed that some files were missing from my OMV NAS then i noticed a strange noice ( the HDD loop noise) in a disk.
We had some power losses some days ago and propably the disk failed
I bought a new 3TB WD disk to replace it but i cannot do it through UI. I cannot see the inactive raid

I tried to add the new HDD from ssh but i couldnt
The new disk is the sdi.
i am 99% that the raid is raid5.

Thanks
