ZFS is in a degraded state

[David Simpson]

Early this morning I received this error notification in my email:

"The volume Drive (ZFS) state is DEGRADED: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to continue functioning in a degraded state."

After logging into my Freenas under the storage and a few places and I can't find anything wrong. Does the Freenas automatically fix this? Do I need to scrub or do anything to be safe?

Please post the results from: zpool status -v in code tags

@gpsguy here it is, I don't see anything that indicates what that email references. Also, am I scrubbing enough?

Code:

[root@freenas ~]# zpool status -v

Did you reboot after getting the message?

 

[SweetAndLow]

Smart test data, hardware and freenas version like the forum rules say to provide with every thread.

 

[maglin]

your scrubs are resilvering but the scrub doesn't show any run time which leads me to believe the scrub is getting stopped. Usually not running enough RAM will do this. Also the boot drive is showing scrubbed in 0h0m. Something is a miss here.

 

[Ericloewe]

Also the boot drive is showing scrubbed in 0h0m. Something is a miss here.

Code:

  pool: freenas-boot

  scan: scrub repaired 0 in 0h0m with 0 errors on Tue Jun 28 03:45:07 2016

Hardly unusual with a decent boot device. ;)

I've never looked at boot scrub times. It too scrubs in 0H0M. But the Drive pool still finished it's scrub in 0h0m which is saying something is amiss.

I'm thinking reboot. Voluntary or otherwise. It explains why the counts are all zero.

I have a Freenas Mini with FN 9.1 Stable, and hadn't restarted it until last night. So should I presume everything is ok? SMART says everything is healthy, I will post a screenshot of that later

 

[philhu]

go into a shell, type: uptime

That will tell you if it rebooted

 

[David Simpson]

Will do @philhu if it did reboot is that when it would have self repaired the degraded state when it came back up?

 

[philhu]

If it rebooted, it could be a transient error, and it 'fixed' itself

Look in dmesg also, see if it shows wierd stuff at the bottom of the file

Freenas Mini with FN 9.1 Stable

9.1, or 9.10? They're very different. And if 9.10, which exact build?
