Hi All,

 

I am running unRAID Pro 4.7 with three WD EARS 2TB drives. I ran pre-clears on all the drives (no jumper, preclear_disk.sh 1.6 using the 'A'  option) and they checked out ok.

 

When I set the initial devices, the parity check begins and the data drives are successfully fotmated. At about 2-3% into the parity check, I start to get an error count on one of the drives. I stopped the check, opened the case and re-positioned the drive (by it's serial number) to use a different power plug and SATA cable.  I booted the array at which point the configuration was invalid so I ran 'initconfig' and re setup the devices and the parity check begun again. Again at about 2-3% into the check, the same drive starts accumulating an error count.

 

Syslog attached.

 

My question is, in your opinion, should I RMA this drive?

 

TIA,

Rick

syslog.zip

get a smart report on the drive, but it is getting lots of un-readable sector errors.

 

Look for sectors pending re-allocation, or sectors already re-allocated.

 

Then, make your decision if an RMA is warranted.

Thanks Joe,

 

SMART report attached. I did not know which options to use with 'smartctl' so I used '--all'

 

I also tried '--test=short' and '--test=long' but both of those commands came back to the shell prompt immediately without reporting anything.

 

I cannot tell for sure if the drive is bad but it looks like it.

 

What do you think?

smartctl.txt

there are 204 sectors pending re-allocation, but none have been re-allocated as of yet, since they have not yet been written.

197 Current_Pending_Sector  0x0032  200  200  000    Old_age  Always      -      204

 

The "long" ans "short" tests initiate those respective tests.  You must get a status report after waiting for their completion.

However, both have aborted on the first "read" failure they encountered.

Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error

# 1  Short offline      Completed: read failure      90%        41        124593828

# 2  Extended offline    Completed: read failure      90%        41        124593831

# 3  Extended offline    Completed: read failure      90%        41        124593824

 

Basically, time to RMA the drive.

Joe,

 

Thanks again for the speedy analysis.

 

I will RMA.
