Hey everyone. I'm not a linux wiz or know a lot of commands. I get the basics. I have OMV 3.0.94. I have 5 physical drives, 1 160gb boot drive and 4 3tb WD drives setup in RAID 5. I don't know when it happened but my raid array just stopped working. I couldn't tell you when since I dont access this system regularly. It is used as a backup of backup source. All drives are showing up in the bios, in the web gui and in other places when commands are used. I went ahead with this post (Degraded or missing raid array questions) to provide this info:

I'm not really sure where to go from here since I really don't know what to search for. I've attempted to search to rebuild the raid array but I'm not sure. Any help or guidance would be appreciated. I would prefer to attempt to save the raid, if possible.
