My hard drives keep failing and I'm worried of losing everything. I have dual parity, so I only lose everything if a third disk fails, but it's still worrying. Basically, here's what happened: 1. Disk 5 failed 2. I replaced Disk 5 with a pre-cleared hard drive, following all the manual instructions 3. A week later, disk 6 failed. I thought this was an unlucky coincidence 4. I replaced disk 6 exactly as I did previously. The array rebuilt successfully 5. A few days later disk 6 failed again. I knew that my new pre-cleared hard drive wasn't the issue here, so I unassigned disk 6 and then reassigned it to the array (again following the manual instructions) 6. At this point, as the array was rebuilding disk 6, disk 8 failed. 7. Now the parity is all rebuilt, but disk 8 is obviously still failed. tower-diagnostics-20221128-1809.zip FYI: All of the hard drives being used in this NAS (parity and disks) are Seagate EXOS 16TB disks. What should I do? I will check the power supply to the NAS chassis and the ethernet cable, as that's what some other forums point to. I will keep things posted here, but if you have any other ideas please let me know. Attached are the diagnostics. Thanks

Yes I meant 250 gigbytes The data consisted of protools sessions

Sorry what I meant is: 1. I copied 250gb to the cache pool. This wrote at 70MB/s 2. Once this was done I used the 'Mover' to move the data from the cache pool to the array. 3. As this was moving, the CPU spiked from 5% to 100% 4. The NAS was not being used in any other way at this time

Update: As a test I tried moving some data directly into the cache pool (not using a third party backup software), which was super quick (≈70MB/s), but then as mover settings kicked in the CPU went mad, kept jumping from 5% to 100%...

My NAS server is extremely slow at writing data... slower than it should be. We're currently writing data to it at about .05-4MB/s. Here's the sitch: - We've got the Storinator 45 drives - Everything is looking "healthy" on the unraid interface - I don't have turbowrite set up, but even without this feature, the NAS is being way too slow - I'm not using the cache pool either, but again this write speed is abnormal - Using third party apps to write to the NAS (chronosync and carbon copy cloner - both up to date) - Slow on all computers connected to the NAS - Have checked the connections to the Network and have ruled this out as an issue - I have 4x 16TB EXOS drives from Seagate used for storage + 2x 16TB EXOS drives used as parity drives

I'll repost in the correct forum section

Ha oh right, silly me It's unraid V6.8.3

Hmm I'm not actually sure... My colleague who is no longer here set this up. Do you know how I can check? Thanks
