February 2, 20242 yr Hello, I've just built a new NAS and got UnRaid up and running. I've basically done a modified version of the NAS killer 5.0. Everything mostly seems fine but I've had a couple weird issues. The entire array except the parity has gone into unmounted:unknown file system a couple times. It did it once after a clean shutdown. The other time it just did it randomly after running fine for several days. Both times I just reformated the disks because I don't have any important data on them right now. This is obviously not making me want to store anything important on it yet because it doesn't seem stable. The other odd thing is that my test share I set up seemed to be operating fine while the 6 array disks were unmounted. I believe the files were still on the cache drive though so maybe that explains it. Could it be my Adaptec HBA card causing issues?

February 5, 20242 yr Author nas-diagnostics-20240205-1337.zip took the NAS offline this weekend, clean shutdown. After powering back up only the parity and cache are mounted. The 6 other disks are back in unmountable:unsupported partition layout. Edited February 5, 20242 yr by DutchDillon
February 6, 20242 yr Community Expert This has been known to happen with those Adaptec controllers, you should be able to recover by rebuilding the disks one buy one, but I would recommend replacing that controller ASAP.
