Hi

When I startup, I receive the Mesage: "[FAILED] Failed to start zfs-import_port ZFS pools by device scanning."

I can check the Service with the command:
systemctl --failed

The result is:
Bash:
  UNIT                    LOAD   ACTIVE SUB    DESCRIPTION
● zfs-import-scan.service loaded failed failed Import ZFS pools by device scanning

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
1 loaded units listed.

When I check with zpool status, I see this result:
Bash:
╰─○ zpool status
  pool: rpool
 state: ONLINE
  scan: scrub repaired 0B in 00:01:04 with 0 errors on Sun Sep  8 00:25:05 2024

errors: No known data errors

I'm not sure, what this exactly means.
My Proxmox PVE seems to run despite this message fine.
At least, I didn't recognized any failures or errors.

But I still want to understand the problem and if possible, resolve it.

I have the the details for my machine here:

Proxmox VE
Version 8.2.7
Installed on a Minis Forum MS-01 Machine.
I have installed one NVME Samsung SSD 970 EVO Plus 1TB as system disk, where Proxmox is installed on. Formated as ZFS.
And also a second SATA Samsung SSD 870 QVO 8TB which is installed on a Delock SATA III PCIe storage controller.

The 8TB SSD is reserved for my TrueNAS Scale VM. I made a passthrough for this SSD for the VM with the command qm set 120 -scsi2 /dev/disk/by-id/ata-Samsung_SSD_870_QVO_8TB_S5SSNF0WA00303W,serial=S5SSNF0WA00303W. Could it be, that this passthrough is maybe related to my issue? Just guessing.


This is the output from lsblk -o NAME,MODEL,SIZE
Bash:

Did you ever figure out what this error means? I also get the error during bootup of Proxmox. My boot drives are setup as a ZFS mirror.
