Proxmox VE 7 add ZFS SSD disk.

[Saturn]

I'm ready to repeat the experiment, resuming a copy of the disc. I want a working migration method if it still exists.

You probably wiped that while trying to import it with "Datacenter -> YourNode -> Disks -> ZFS -> Add"?
Then I would destroy that pool zpool destroy Micron960 on N2, destroy that virtual disk, add a copy of it again from your N1 Node and try it again with zpool import -f Micron960 and then see if zfs list is then showing your "vm-100-disk-0" zvol.

Okay I'll make a copy now and repeat the process by deleting the imported pool

 

[Saturn]

For the purity of the experiment, I completely recreated Proxmox N 2 and added the file. And hooray, it worked! I re-created "zpool destroy Micron960" to show that it is empty. The only question left is why the first time did not work....

Here I checked on the system in which the disk died during operation, the data was on another disk, so when connecting this disk, the command "zpool import" does not output anything, although the disk is visible in the system and the same partitions as in the original one are visible. Perhaps you need to test such a disk with some tools.. Can you tell me how?

 

[Saturn]

That's how the pool looked in the deceased system, so there was a single-disk pool on a separate physical disk.

 

[Saturn]

And so it is visible in the new system. As you can see from the screenshot, it is not imported and it is not at all clear how to work with this pool.

The most interesting thing is that the disk with ext4 survived the failure of the system disk and did not lose information, and the disk with zfs in an incomprehensible state and most of all there are questions whether it is worth using zfs pool single disk when creating or it is fraught with consequences, as in this case.
