Error importing pool

[sharle]

Hi!
The error occurs when the server crashes. After starting the system, it showed the message "Pool is offline"
EXPORT/IMPORT in offline pool mode was successful.
When importing a pool, it reports a “non-unique disk number” and displays an error on the screens.
Help urgently!!!!!

Please describe all your hardware completely.. Including how the disks are wired to the system board, manufacture of disks, and model of disks. Plus your TrueNAS version.

Their are several un-supported hardware configurations that can lead to non-unique disk serial numbers.

TrueNAS CORE TrueNAS-13.0-U1 HP proliant dl380p gen8 HDD manufacturer I don’t know. The server is turned on. Run by other VMs

Edit : it seems this ticks all the "not advised" boxes.
Hardware raid...
Using vmware....
Hope you have a good backup....

I agree with @Alecmascot, you have built a server to self destruct.

Hardware RAID-5 is not supported on TrueNAS. In fact, it tends to eat data when used with ZFS. Or even damage the entire pool beyond easy recovery.

Using TrueNAS under VMWare requires very specific things to be reliable. You did not pass the disk controller with the disks through to the TrueNAS VM. That can and DOES cause pool corruption.

While you might be able to recover your pool, in my opinion, if you don't have the skills to proceed, it is time to restore from backup.
