Errors on Daily report am I in trouble?

[Hammerz]

Tonight I got this:

Checking status of zfs pools:
pool: Vault
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
see: http://www.sun.com/msg/ZFS-8000-9P
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
Vault ONLINE 0 0 0
raidz1 ONLINE 0 0 0

ada3p2 ONLINE 0 0 0
ada4p2 ONLINE 0 0 0

errors: No known data errors

Am I ok? or is that a big problem? array is brand new so im hoping there was just a mismatch but I am not very knowledgeable on this?

Hi Hammerz

SSH into your filer and run:

smartctl -i -H -A -l error /dev/ada5

and see what it reports. That command runs a SMART test against the complaining drive with the following options:

# -i = Device Info (Does not force a drive spinup)
# -H = Device Health (Forces spinup)
# -A = Only Vendor specific SMART attributes (Forces spinup)
# -l error = SMART Error Log (Forces spinup)

and reports back some attribute details and a summary assessment of the drives health.

If you can you could also shutdown the box & run the manufacturers test utility against it. Personally I think SMART might give less biased results, but if the mfgs. utility says the drive is bad you should get it replaced ASAP. If neither test is conclusive in the "badness" of the drive keep a copy of the results\output of the SMART test you run now for comparison later.

It's an uncomfortable situation to be in because you really shouldn't have any data corrected by a scrub in a properly functioning system, but without definitively dead hardware it might be tough to get the part replaced. Of course if the hardware is brand new it would be worthwhile to inquire with the vendor about swapping it out.
