I am getting this error: "Out Of Memory errors detected on your server". I have 512GB RAM so I'm not sure how this can be happening. I wonder if some process is hanging and using up all the memory?

@trurl so what is recommended? Have each disk presented separately in the array and just divide up what shares should use certain disks? If that is the recommended design then I can approach that option after (hopefully) I am able to recover and back up my data in the current format. Do you have any suggestions on how to proceed considering my current situation?

Please help! Disk1 showing as Unmountable: Wrong or no file system I got a free Dell R710 a few months ago. I added 8 brand new 5TB 2.5" drives which are setup as one virtual disk (Disk1) on the server and Unraid sees all the drives as one 40TB drive (disk 1 in array - btrfs). It has been working fine for about 3? months and then a day or two ago it is showing up as "unmountable: wrong or no file system". When I stop the array and attempt to mount the disk1 unassigned device it does not mount. I am not sure what to look for or what to try. Any help is welcomed and greatly appreciated. Diagnostics ZIP is included. Please let me know if you need anything else to help troubleshoot.
