I have 4544 errors on the parity drive.

 

Diagnostics are attached, where I can see a LOT of read errors on the parity drive.

 

Time to replace it right ?

 

I can't find the procedure to replace a parity drive on the wiki, is it similar to the one for a new data drive ?

 

1. Stop the array
2. Unassign the parity drive if still assigned (to unassign, set it to No Device)
3. Power down
4. [ Optional ] Pull the parity drive (you may want to leave it installed for Preclearing or testing)
5. Install the new drive
6. Power on
7. Assign the new drive in the slot of the parity drive
8. Go to the Main -> Array Operation section
9. Put a check in the Yes, I'm sure checkbox (next to the information indicating the drive will be rebuilt), and click the Start button (or similar)
10. The rebuild will begin, with hefty disk activity on all drives, lots of writes on the new drive and lots of reads on all other drives

Yes, replace:

 

197 Current_Pending_Sector  0x0032   200   200   000    Old_age   Always       -       45

You can skip some steps:

 

1: Power down

2: Remove old parity and install the new drive

3: Power on

4: Assign the new drive in the slot of the parity drive and start array to begin parity sync

 

 

Thanks johnnie.black, followed these steps and parity rebuild has already finished.

 

All is good now
