freenas-boot pool labeled as "DEGRADED" straight after installation on a new SSD

[dilod97118]

Hello, I've just finished installing FreeNAS on my new NAS box. Everything worked flawlessly until I tried scrubbing the boot pool. I tried reinstalling the system 3 times, used different flash drives. I checked the ISO file's checksum too.
The system has 32TB of storage (in RAID-Z2) and 16GB of ECC-RAM.
This is the output of 'zpool status -vx':

Code:

  pool: freenas-boot
 state: DEGRADED
status: One or more devices has experienced an error resulting in data
    corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
    entire pool from backup.

The system SSD is a new 120 GB Western Digital Green mSata drive (WDS120G2G0B).
What is the source of this problem?
Is there any way for me to fix it?

Thanks

Sounds like you have a bad boot SSD. It happens.

 

[dilod97118]

Yeah, but it passes the SMART tests, even the long one. Also, this is a completely new drive. Should I just replace it?

 

[Samuel Tai]

Yes. You unfortunately ran into the front side of the drive failure bathtub curve, and encountered infant mortality.

 

[Samuel Tai]

For the next SSD, try a Red instead of a Green.

 

[dilod97118]

I use Red Pros for my actual storage pool, thanks for the suggestion. I will also try to install the OS onto a flash stick to see if the problem goes away on a different drive.

 

[Samuel Tai]

The thumb drive will die even faster, unfortunately, as thumb drives just don't have the cells to handle FreeNAS's write patterns with any longevity.

 

[dilod97118]

I know, I just want to test to see if the SSD is broken. If it works on the flash drive for a few hours, I will just replace the SSD and use that.
