In Truenas 25.10.2.1, I have a pool that was originally created at the CLI as part of of a data migration. It was then imported to the Truenas GUI, and the names of the disks show as sdb, sdc, etc., whereas in my other pools, the names of the disks show as unique IDs.
My concern is that the sdb, sdc, etc. designation can shuffle after reboots. I have tried exporting this pool and, at the CLI, importing with the command “zpool import -d /dev/disk/by-id/ <pool_name>”. This will cause the disks to be designated with unique IDs at the CLI, but then when I export the pool and import it again at the GUI, the names are back to sdb, sdc, etc.
Here is my question: Is this really a problem? Note that in the GUI, even though the disk names show as sdb, sdc, etc. when I click on “View Vdevs,” if I then click on :”Disk info,’ “Edit” for a specific disk, it shows the name (such as “sdb”) and the serial number. In fact, the “name” field appears to be editable, so perhaps I could even change the name to the serial number or unique ID. Does anyone have any suggestions about this? Perhaps it’s not even anything that’s likely to be a problem.
