Swapped to LSI card and problems are gone. Full 200+MB/s sync and formatting worked way faster too. I wouldn't recommend anyone run an Adaptec card after my experience.

I talked to some people that are using the Adaptec HBA card and having issues as well so I'm going to swap to an LSI model.

Didn't get a chance to run the diskspeed check. However, after some troubleshooting it's appearing to be a cabling issue. I pulled power from the top 4 drives and the parity-sync hit 130MB/s. Thinking it was the SATA power splitter I pulled that and just ran power off the remaining PSU cables... but the sync dropped back down to 9MB/s. I guess the next thing to try is swapping out the Mini SAS cable feeding those 4 drives.

I put it in maintenance mode and restarted the sync. No speed difference. I'm having a recurring issue with the drives going unmounted: partition layout after reboot as well. I've changed out HBA cards, mobo, processor, RAM. Not sure what else to try at this point. Cabling, drives, or the HBA model I guess.

HI I've got a new build and the parity check speed seems extremely slow compared to what i've seen on others. I'm only getting 9MB/s on a 6TB drive at best. It's going to take 8 days to complete. biernas-diagnostics-20240213-1013.zip

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.

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?
