Unraid 4.5.6 Parity Check Error

Featured Replies

Hi guys. I have a problem. I am running a parity check on my config.

My specs are intel c2d e4300 + gigabyte p35-DS3 + 2 X 1gb ddr800.

My harddisk are :

 

Parity . 1.5tb WD

DISK 1 . 1tb WD

DISK 2 . 1tb Seagate.

 

The parity check runs fine all the way to 50+%. Its running at speeds of avg 90,000kb/s

Soon after the speeds drop drastically and the errors pop up.

 

Here is a screenshot of the gui in explorer

Whats the problem here. Can anyone help me please.  Thanks a million

 

Did you run PRECLEAR on the drives to make sure the drives weren't dieing before you started using them in the array?

 

Your parity drive is reporting massive numbers of  "media errors"

 

(un-correctable "UNC" errors.)

 

You can confirm this with a SMART report. Look for re-allocated sectors, and sectors pending re-allocation in the attributes.  The "RAW" column for those two will give the counts  (on most properly working drives, the count will be zero).

 

To get a SMART report, type:

smartctl -a -d ata /dev/sda

 

The fix if you see large number of sectors re-allocated or pending re-allocation is easy.  Replace the parity drive.
