Zpool import - disk offline ?

[mkukoleca]

Hello guys. I have a 6 drive RAIDZ-1 setup. Was replacing one drive (probably gptid/47af1739) and after booting, pool was OFFLINE/Data not available.

A ssh-ed into my server and it shows that gptid/4766b1cd is offline ?!

Code:

root@truenas[~]# zpool import
   pool: Kukoleca
     id: 9915218132335776628
  state: UNAVAIL
status: One or more devices are missing from the system.
 action: The pool cannot be imported. Attach the missing
        devices and try again.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-3C
 config:


        Kukoleca                                        UNAVAIL  insufficient replicas
          raidz1-0                                      UNAVAIL  insufficient replicas
            gptid/4766b1cd-fd2b-11eb-b130-e0d55e1a567a  OFFLINE

            gptid/47af1739-fd2b-11eb-b130-e0d55e1a567a  UNAVAIL  cannot open

            gptid/977351fb-4d4b-11ec-8f9f-e0d55e1a567a  ONLINE

But gptid/4766b1cd is present (ADA3):

Code:

root@truenas[~]# glabel status
                                      Name  Status  Components

gptid/47172efe-fd2b-11eb-b130-e0d55e1a567a     N/A  ada0p1

How can I get it online and import the pool? Any help? Much appreciated. Thank you all in advance.

Regards, Miroslav.

Check your drive cabling. Usually when a drive goes offline, there's a cabling issue.

 

[mkukoleca]

Thank you, Samuel. Changed SATA cable. Issue remains the same :(

 

[Samuel Tai]

Try shuffling your offline drive to another port. It could be you have a bad port. If the drive comes online on another port, but the drive that shuffled to its old port goes offline, that's an indicator of a failed port.

Samuel, thank you for your suggestions. Tried, but to no avail :(
Is there a command to bring device back to online status?

 

[Samuel Tai]

Yes, but I don't know if it will work with your pool in an non-imported state. Try zpool online Kukoleca gptid/4766b1cd-fd2b-11eb-b130-e0d55e1a567a. Since the offline status persists, it's likely you offlined the wrong drive.

Code:

root@truenas[~]# zpool online Kukoleca gptid/4766b1cd-fd2b-11eb-b130-e0d55e1a567a
cannot open 'Kukoleca': no such pool

Try shutting down, and removing the power cord until all capacitors drain. Then power up again.

Tried. No luck :(
