Volume DEGRADED, no SMART failure.

dvc9 · Jun 26, 2019

Hey!
I have a bit of a bug here. We have one VDEV, that is degraded,
but mostly all disks shows great stats in SMART, and SMART -short tests.
One drive /dev/da46 did not pass smart, so we are now replacing it.

I have printed out here gpart, camcontrol, zpool status, and messages.

FreeNAS-11.2-U3
Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz (12 cores)
at the moment only 32 GB RAM. ( ECC )

What have triggered it ?
We did upgrade the RAM, but now we have taken out it all just to leave 2 RAM peaces, just in case its RAM.
We have installed a SolarFlare NIC 10 GbE.

that's the only two things done lately.

So the question, The pool works even if its degraded...
but how can I identify and clear the errors.

zpool status

Code:

root@storage01[~]# zpool status
  pool: freenas-boot

We had just updated to 128 GB RAM, and one of the chips where faulty.
We then downgraded to 32 GB RAM, and it did not get new checksum errors,
but the old ones where still there...

I therefor believed that its a "lag" of some sorts, as the files where idle,
and the corruption has actually been removed.

So I followed up on Oracles documentation. ( Repairing ZFS Storage Pool-Wide Damage )

and ran the
zpool clear -F PoolNAME

This is as the errors where only checksum,
no smart errors, and no disk errors that I could find.

If the error occurs again, then I must reconsider.

It's a good practice to burn-in new hardware (especially RAM and HDD). Did you burn-in the new memory before using it?
How did you identify the faulty memory?
To know if this could have been detected by a burn in...

danb35 · Jun 26, 2019

So zpool clear doesn't actually fix anything, it just takes away the report of errors. A better thing to have done would have been a scrub, as it would check if the errors had actually been resolved (and if so, reset the counter).

dvc9 · Jun 26, 2019

Yeah, so did not test the RAM before adding it ( shame on me )
The scrub will be started as soon as the Resilver of the failed drive is done.

Important Announcement for the TrueNAS Community.

Volume DEGRADED, no SMART failure.
