Hi

 

i have a weird problem.

 

i got a small unraid nas with 1 parity disk and 1 data drive + cache running on the stable version of unraid (6.8.3)

 

everything work fine but now, i have a problem.

yesterday, my usb drive crash. i restore an old backup (with backup and restore).

 

the nas start, i chose my data drive 8tb and now, the parity disk are detected as a 4tb drive.

i check with lshw in the unraid terminal to check for a possible bug and no, the drive are  still detected as a 4tb.

 

i try with the last beta available. but the drive are still detected as a 4tb. i revert to the stable version.

 

when i received the drive. i preclear it 

Preclear: total elapsed time: 93:14:47

 

the drive are only 2-3 month old.

 

do you have any idea how to fix this or if the drive are dead and need warranty replacement ?

 

Thanks

 

John

Are you sure that the backup is not from a time when you DID have a 4TB parity drive?    The SMART report agrees that it is a 4TB drive.

this is my most recent flash backup.

 

if i put my old bakcup 2020 05 07

the drive are still detected as 4tb

Presumably, the drive you're having problems with is the one you've separately attached SMART for.  It IS a 4TB  (ST4000VN008)

thanks, 

 

i will rma this hard drive.
