Recently upgraded to 6.12.13 (more than a week).

After starting the system, was greeted with above message.

I have tried to reboot multiple times though the array is still offline.

 

ZFS isn't up either.

I don't see any flash drive related errors, were the diags saved when it was showing it?

[sabertooth]

Afraid, I saved after the reboot
How do I correctly restore installation along with the config?

If you mean the flash config, you can restore from a backup, if available, copy the complete /config folder.

[sabertooth]

No back-up, but after copying the /config folder, the array doesn't start along with the zfs pool.

Will try again

Post a screenshot of main

Please find the screenshots as attached.

Need the complete page, including why you cannot start the array, there should be an error.

Sorry @JorgeB about the delay in reply. I started to explore various options to restore the zpool.

 

After a fresh install on the same USB drive followed by copy of the /config folder the array would fail to start including the zpool.

Manual start of the array would indeed start the main Unraid array though not the zpool based one since same wasn't recognized by Unraid.

I had to manually configure the zpool by adding a new pool and adding the existing HDDs to the array.

This thankfully restored the zfs pool.

 

Regarding the auto-start issue, apparently the Settings::Disk Settings:Enable auto start was disabled after the first error message (relating to corruption of USB drive). Once enabled array would restart after a reboot.

 

Having said that I believe there is indeed an issue with zpool config restoration after copying over the /config folder.

[JorgeB]

Possibly the pool cfg files were missing or corrupt, but if I understood correctly, the issue is resolved?

[sabertooth]

Yes, thank you.
What is the location of pool cfg ?

 

[JorgeB]

/config/pools
