Hi,

I set up a TrueNAS system around the second week of march, and i have JUST discovered that it has sent me a notification on 29th of March, that one of the drive is 'degraded because of persistent errors'.

Running zpool status -v results in:


Code:
root@truenas[~]# zpool status -v
  pool: FirstPool
 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.
  scan: scrub repaired 0B in 00:14:59 with 0 errors on Sat Apr 17 00:14:59 2021
config:

        NAME                                            STATE     READ WRITE CKSUM

          raidz1-0                                      DEGRADED     0     0 0

and then i ran: smartctl -a /dev/ada3

is there anything i can do to help this? or should i just get a replacement drive?

Thank you!!

Run a smart check on all your drives and post the output here. Complete hardware specs and TrueNAS version would be helpful as well.

I bought 4 x 4TB Western Digital NAS drives and 3 were bad within first day. 2 of those were DOA. It happens.

You might consider looking at dmesg for CAM information... that may point you in a clearer direction if the disks are actually OK (which you should check with SMART)
