Replacing disks

[Jarrodr]

Hi All,

 

I bought a 4tb to replacement my Parity, I haven't installed yet though.

 

I have a dilemma,

 

 

Issue:

I have a corrupt disk and want to replace it.

 

Requirement:

Parity - 4tb (new)

Disk 1 - remains the same.

Disk - 3tb (using the old parity drive)

 

How do I replace the parity and disk with losing data?

Parity swap.

Step 1: Parity swap

Step 2: Swap disk 2

[JorgeB]

When complete the parity swap procedure will have replaced both disks.

For some reason the phrase Parity Swap is not acting as a hyperlink to the relevant part of the documentation, so here is the link.

The disk is disabled, not corrupt. If it were corrupt, filesystem repair would be the correct fix, rebuilding from parity typically won't fix filesystem corruption.

 

Emulated disk2 has 1.5+ TB contents.

 

Disk2 does look like it should have been replaced before now, assuming that is the SMART report for disk2 you attached. Can't confirm since screenshot doesn't show serial.

 

Do you have Notifications setup to alert you by email or other agent as soon as a problem is detected?

 

Do any of your other disks have SMART warnings on the Dashboard page?

 

Attach Diagnostics to your NEXT post in this thread.

Here is the smart report for Disk 1 attached.

 

Where can I find the Notification history?

The Dashboard warning is for UDMA CRC, which is connection problem some time in the past. You can acknowledge it by clicking 👎

and it will warn again if it increases.

 

Since it is WD disk I am wondering about attributes 1 and 200 for that disk.

 

Why are you doing read-check?

Sorry, this is what I see.

I actually cancelled that check now

and you should, you apparently don't have it notifying you about disk problems

@trurl

 

Not sure if this helps, I picked it up.

 

 

I followed this yesterday, and no luck. Took some time.

Apparently nobody reads the documentation    All the necessary steps are covered in this section of the online documentation accessible via the ‘Manual’ link at the bottom of the GUI.

By the way, I just picked up my 4tb hard drive. Haven't installed it yet.

Do you mean you were trying to rebuild to the same disk? Why?

Replace disk2 with another disk.

Replace disk2 with another disk.

Was hoping for a miracle :-|.

 

Will have to replace the parity with the new drive first and then use the old parity drive as disk 2.

Parity looks fine. If you want to use a disk larger than parity you would have to do parity swap. That is not at all the same as replacing parity first.

 

Please tell us what you want to do so we can make sure you are going to do the right thing.

No need to replace parity

You can't replace parity since you already have disabled disk.

Let us know what you want to do

[Jarrodr]

Resolved.

 

Installed the new drive. With the array off, assign the new drive as a parity and old parity as a new disk.

Start array, it copies the parity then installs the new disk.
