I've checked all cables and they're connected firmly. Disk is rebuilding currently, I think I'm gonna replace the SAS controller as a precaution. Too many weird disk issues in the last few months.

Hey, thanks @JorgeB I was thinking this but I replaced all the SAS cables with higher quality lock in cables and double checked power connections a couple months ago, uptime is 1 month 15 days without issues. I'll give it a reboot and see what happens.

Seems I also cannot get my array to stop.

Hey all, Would someone be able to advise me please. Is this a sign of a failing disk or some weird SAS controller bug? I had two drives fail a couple of months ago and now i'm thinking either my SAS controller is the issue or i'm really unlucky 😂 Thank you for any help or suggestions. dansunraidnas-diagnostics-20230315-1817.zip

Fixed 👍 thank you again

I've noticed something weird. Seems to be stuck like this.

Really good suggestions, thank you! My appdata is set to use cache only, not sure why I have some "bytes" in the array? Domains is just a backup of the VM vdisks I have running on the unassigned NVME drives so I dont have it in cache "only". Unfortunately I am making use of one the unassigned SSDs right now and have plans for the other unassigned SSD. I don't know why I had not set system to cache only, I have done this now but probably need to move the files back to cache.

Oops, here's the correct diagnostics 🙂 dansunraidnas-diagnostics-20230127-2050.zip

So everything is back to normal 🎉 Thank you everyone for the help and support. dansunraidnas-diagnostics-20230127-1851.zip

Not long now.

Apologies, please see attached. Rebuild of disk 8, the second disk to fail, is still underway. The array is live, the data that originally disappeared (when the first error with disk 7 occurred) is back, which is really positive. Disk 8 was emulated immediately when it failed so I didn't notice any data loss the second time. dansunraidnas-diagnostics-20230125-2349.zip

Disk 8 is rebuilding, no other issues so far.

Thank you for your help 🙂 I really appreciate your knowledge and suggestions. I'm going to go ahead and replace disk 8 now and rebuild it hopefully without any more issues 🤞

Interesting, is that an issue?

I haven't replaced disk 8 yet (I replaced disk 7 first as it was the initial problem disk with filesystem corruption), I'm going to change some SAS cables and insert a new drive to replace disk 8 then start the rebuild soon. I will provide updates.
