I created a RAID 5 array with the RAID Management tab from OMV 5, then I encrypted that array and then I created the biggest filesystem possible. If I reboot OMV, that filesystem is only available when I decrypt the array.
My problem is I just realized by trying different things with Virtualbox (removing one disk from the array and adding a new empty one) that if I lose one disk I can't rebuild the RAID array with a new disk (the Recover button is greyed and my array disappeared), am I wrong? Is it because I encrypted the array afterward? I thought once the array is created the RAID 5 would just act on encrypted data like it would on unencrypted and it would not matter.
I don't have enough space to backup what's on that array elsewhere, so before reinstalling OMV (one my docker container don't work as it should anymore and I don't know enough to fix it) on my system drive I wanted to try in a virtual machine and now I'm worried if one drive fails I lose all my data.
