Volume 1 state is Degraded. One or more devices has been removed

[bernd67]

Thx a LOT for help!
Here we are...

[root@freenas ~]# zpool status

pool: Volume1
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.

http://illumos.org/msg/ZFS-8000-2Q tells me:

a.)
Should i perform:
action: Attach the missing device and online it using 'zpool online'.

b.)
Determine which device failed to open by looking for a FAULTED device with an additional 'cannot open' message
->> There is none marked with Faulted or Message "cannot open"

c.)
Or should i perform this command:
If the device has been replaced by another disk in the same physical slot, then the device can be replaced using a single argument to the 'zpool replace' command:
# zpool replace test ada0 ? -- ((S2H7JXOD10032..))

d.)
What exactly does this mean:

"gptid/eb0192da-0536-11e4-bcda-f46d045fb8XX"
"gptid/e3aae27d-9309-11e7-b6c3-54a0508006XX "

" was /dev/gptid/eb986d1e-0536-11e4-bcda-f46d045fb8XX"
?

e.) OK, that makes it a bit clearer, not the Ethernet Cable.. will try and replace all SATA cables, but i had no broken SATA cable so far in
Pc's...? Problem could be that i have only 2 SATA Ports on my Mainboard?
Oh seems i am lucky:

https://icecat.biz/rest/product-pdf?productId=9014568&lang=de_at

SATA II Anschlüsse 4
so i could maybe move both Hard Disk Serial ATA cables to another Port.

f.)
1.)I tried first to boot only with one of the old Hard Disks previous inside NAS only, was able to perform that and get the Web Access
2.)I then tried the same with the other old Hard Disk previous inside NAS, NO! Access to Web Access!
3.)Afterwards tried with one Old Hard Disk and one replaced used Hard Disk - was able to get Web Access.
ok, maybe i waited to little Time on 2.) - Or is no Web Access the same as "Disk damaged"?

 

[NugentS]

The problem with SATA cables is that they are not designed for lots of usage. Thus they after being plugged in a few times may distort and make bad connections. This CAN (but not always) cause the chksum errors you saw. Thus I suggested use a new cable to attach to the disk and if possible try a different port

 

[bernd67]

So i should reenter the old meant to be defected assumed disk and change cables and if possible ports?
or only change cables and if possible ports now?

 

[NugentS]

No, now as you are halfway through replacing the drive - you should complete that
Then test the old drive on a different system through SMART and perhaps badblocks or equivalent so you can decide if the drive is broken or OK

 

[bernd67]

Hello Forum,
How could i perform a SMART check then, maybe using my little Test PC with MX Linux?
I assume i have to take an usb Adapter and mount the disk using mount -t Name /...... ???
Which command exactly to give there as mount command and as Smart command ?
smartctl -a /dev/ ??

 

[bernd67]

Hello Forum,

My Pool Name is Volume1.
I have replaced faulty ada0 device.
therefore i had assumed i have to online the new disk using:

[root@freenas ~]# zpool online Volume1 ada0

but i get:

cannot online ada0: no such device in pool ??

[NugentS]

I am sorry, but I have completely lost track of what you are doing how and why.
Please post in code blocks:
1. zpool status -v
2. glabel status

 

[bernd67]

Thank you, NugentS!
Yes, true, its a bit confusing now...
Status is that Pool "Volume1" is still degraded...
and i have replaced ada0 Hard Disk with a used spare Hard Disk with same Size and Manufacturer.

Here are the most recent Outputs:

How to proceed to get the Pool online again and Data mirrored again?

 

[sretalla]

action: Attach the missing device and online it using 'zpool online'.

This is not useful information for you since the disk is broken and to be replaced, not brought back as it was.

You should be able to replace the UNAVAIL disk in the GUI and select the new one you inserted to use for that:

10. Storage — FreeNAS®11.3-U5 User Guide Table of Contents

www.ixsystems.com

or

/core/coretutorials/storage/disks/diskreplace/

Depending on your version.

 

[NugentS]

and then please update to TrueNAS 12, but only when everything else is fixed

 

[bernd67]

I have Freenas Version 11.1 - U7 - shown under "Systems"
So i have replaced the wrong disk? I assume not..
A thing i wonder about is that i see no pool entry in "Volume Manager" instead i could configure (new) Volumes there..

10. Storage — FreeNAS®11.3-U5 User Guide Table of Contents

www.ixsystems.com

Before physically removing the failed device, go to Storage ➞ Pools. Select the pool name then click  (Settings). Select Status and locate the failed disk. Then perform these steps: ....

That's what i wrote earlier.. there is no Section Storage -- Pools with a Pool Name!

 

[NugentS]

I am not familiar with the GUI for 11.1 however you do have a pool, called Volume1 according to zpool status
Please post a screenshot of your storage screen

 

[sretalla]

What you'll need to do is to export the pool at the CLI and then import it in the GUI to have the GUI manage it again.

The problem with that is you often can't import a pool that's unhealthy in the GUI.

So we may be back to CLI (and much more complication) to fix it from there.

 

[NugentS]

Ahhh, that would make sense

 

[bernd67]

Thx for further Support. How can i add the Screenshots here? Have i to take them on a Webserver first? cause i
can not upload them from local?

What Command should i enter into CLI then as next command(s)?

 

[bernd67]

Problem still not solved - Help very appreciated.

 

[sretalla]

If you replaced ada0, it looks like you have done so with a disk previously used by Windows.

Wipe that disk (assuming you're confident it's the right one) in the Disks section of the GUI. https://www.ixsystems.com/documentation/freenas/11.1/storage.html#view-disks

Then use it to replace the failed drive. https://www.ixsystems.com/documentation/freenas/11.1/storage.html#replacing-a-failed-drive

It seems to me your confusion was that you were looking at the documentation for 11.3 (not 11.1, which you're using).

 

[bernd67]

Hello.
Glabel status tells
.. Fb858.. ada1
.. D09a3.. .ada0
.. Microsoft reserved Partition.... ada0


But before change of disk
gptid/eb986d1e-0536-11e4-bcda-f46d045fb858 DEGRADED 0 0 391 too many errors

gptid/eb986d1e-0536-11e4-bcda-f46d045fb858 N/A ada0p2

So. .
ada0 ist the one with errors to be exchanged
....
ada0 serialnr s2h7j90b83160..

. .. So why fb858 is still listed after exchange and why is it now listed as ada1?
Should wipe ada0 or 1 now?
Habe i to in mount disk before?
Which command should i use?
Wipe Button found. . .

 

[sretalla]

. .. So why fb858 is still listed after exchange and why is it now listed as ada1?

Forget thinking of the labels as permanent for a specific disk, they can change at boot and it doesn't matter... the gptid is what's important and that sticks to the disk.

I'm seeing ada0 referring to a disk with a Windows partition, so I would wipe that if you intend to use it with TrueNAS (or FreeNAS as you have now).

 

[bernd67]

Wiped disk 0 cause Contained Microsoft Name.. Partition..
