Is my HDD dead

[SavageAUS]

As the title states is my HDD dead?
Unraid is reporting 10,813 errors on this one drive (seems excessive) and the disk is now disabled.

Is the drive dead or perhaps a faulty cable?

I am using a HBA with mini sas to 4 sata if that helps at all.

According to the SMART report the drive failed the extended SMART test which indicates it should be replaced.

That’s what I thought but wanted to be sure. I’ve ordered 2 4tb iron wolf drives. One to replace the failed disk and another to increase parity (currently 3tb). Should I increase parity before replacing the drive? 3tb to 4tb or replace the failed drive first which is a 3tb replacing with a 4tb. 

[itimpi]

You cannot ever have a data drive that is larger than the smallest parity drive!   If you have only 1 parity drive then you cannot upgrade parity while you have a failed data drive.

 

For you special case I would suggest you start by using the parity swap procedure to upgrade parity to 4TB and as part of the same operation replace the failed drive with the 3TB drive from parity.   When that completes you can either add the other new drive as an additional drive in the array or follow the standard procedure for upgrading the size of a data drive that is covered in the online documentation accessible via the Manual link at the bottom of the Unraid GUI.

Ok so if I am reading it correctly I’ll end up doing 2 rebuilds?

Stop the array. 
Unassign the dead drive. 
Start the array to forget drive. 
Stop the array. 
Assign parity drive to dead drive spot.

Install new larger drive and assign to parity. 
Start array. 
Copy old parity to new parity.

Wait for copy. 
Rebuild replaced disk.

Wait. 
Win.

Optional. 
Stop array. 
Replace any other drive with second new larger drive or add second parity. 
Rebuild.

Wait. 

Win. 
 

My steps are very simplified but I believe the order is correct which is what is important.

Once this is all done I’m gutting my system to install a new motherboard and CPU. Ryzen 7 2700x and MSI board. 4 core 8 thread upgraded to 8 core 16 thread. 
I don’t think it be wise to replace motherboard and cpu and do the parity swap all at the same time. But surely the extra cores/threads would help the process?

Unlikely - this process is basically dependent on the disk I/O performance across the drives involved.

[SavageAUS]

Just to update this thread. 
new drives arrived today and parity swap procedure has begun. 
Guess no Plex for me tonight. 
Once this is done it will need to rebuild the replaced disk (old parity) then I plan to either replace another 2TB with a 4TB or add the extra 4TB as a second parity and shrink the array to 6 disks. 
Thoughts? 7 disks 1 parity or 6 + 2?

If you have decent backups I would think that single parity is enough.  I personally only tend to go for dual parity when the number or array disks gets to be something like 10-12 (but I have decent backups in place).  However it is basically your decision to make.

 

It is always worth remembering that backups are still important as although parity can protect against a disk failure it does not protect against other ways to lose data such as File System corruption (perhaps caused by bad hardware), user error, etc.

[SavageAUS]

Update. 
parity swap went well, now unraid is rebuilding the array disk. Then I think it’ll be time for the hardware swap to ryzen 7 2700x. Do you know if Ryzen still has issues with C states? I’m on unraid 6.12.5.

So even though the parity swap went smooth I am having an issue now.

The new HDD has been disabled twice.

First time i just did a rebuild but now this second time has me worried.

I have a short smart test - no issues.

Tried to run 2 long test and it says Interrupted (host reset).

I have upgraded my hardware to a Ryzen 7 2700x and MSI MAG X570S TOMAHAWK MAX WIFI and replaced the mini sas to sata cable.

I have now even tried with the array stopped but still get the same error. Did I get a bad drive?

[JorgeB]

Please post the diagnostics.

[SavageAUS]

I’m running the drive through another pre clear at present to cover all bases. Once pre clear is done I’ll add it back to the array and rebuild parity. If any further errors occur I’ll be sure to post diags. 

[SavageAUS]

Post read at 63% so I’m assuming it’s all going well. 

[SavageAUS]

So the pre clear all went fine. Parity rebuild all went fine. Couple of hours later parity is disabled again. Driving me crazy. I am retesting another parity sync with the same drive connected to the motherboard this time to see if it’s the mini sas to SATA cable.

Added short smart test

[JorgeB]

It's not logged as a disk problem and SMART looks OK, so most likely power/connection issue.

[SavageAUS]

I think my new mini sas to sata cable is a dud on lane 1. Parity drive is connected to motherboard with 0 issues so far. 

[SavageAUS]

Now due to weather or possibly caught the c state bug my server is offline. 
Seller has refunded me for the mini sas to sata cable after pointing them to this thread. 
Now to order a new one and wait till I get home to see what’s going on with my server. My router is online and so is my camera so I know it’s not power related.

Based on that chart and the output below should I turn my memory speed down to 1866? Since I have 4 x 8Gb sticks and a 2nd gen ryzen 7 2700x?

Correct.

Server seems to be running absolutely perfect thank you for all your help.

I have ordered a new mini sas to sata cable so ill see how that goes.

Last question........................for now lol

With the specs in my signature do you think a 550w PSU is enough? If not what do you recommend?

[JorgeB]

Should be if it's a good quality PSU.

[SavageAUS]

It’s a thermaltake smart power 550. So maybe not the best quality. And I am occasionally hearing what sounds like a hard drive power disconnect / reconnect. You know the sound a hard drive makes when you unplug it while powered on, that screech sound.
