My UNRAID is running in PVE, and the system is booted through a USB device for direct booting.

 

I have a raidz pool set up outside the array and cache to store my data.

 

Today I replaced my computer's motherboard and reinstalled PVE, following the original setup to pass through the boot and data disks. When starting the array, the raidz pool has this error "Unmountable: Unsupported or no file system"

 

The diagnostic file is as follows:

Thank you in advance!

Stop array, type:

zpool import -f raid

then

zpool export raid

start array and it should import now.

启动数组，它现在应该导入。

It worked! I successfully hung on my raid pool, thank you very much for your answer.

 

I learned on chatgpt:

Quote

The command 'zpool import -f raid' attempts to import a ZFS storage pool named "raid" forcefully. The -f flag stands for "force" and is used when you want to forcibly import the pool, even if there are potential issues or conflicts.

 

I'm curious what issues or conflict is causing my zpool to not import properly? Is it possible for the forced import to cause data corruption?

Because you are virtualizing Unraid it was considered a new machine:

Aug  1 10:57:38 Tower root: cannot import 'raid': pool was previously in use from another system.
Aug  1 10:57:38 Tower root: Last accessed by pve (hostid=b5b02378) at Tue Aug  1 10:53:41 2023
Aug  1 10:57:38 Tower root: The pool can be imported, use 'zpool import -f' to import the pool.

I see. thankfully it wasn't some other serious mistake.
