Failed to load datasets - 'path' error

TrueNAS General
1

Hey all,

I recently had to recover my boot drive and uploaded my old config to the latest version on TrueNAS Scale 24.10.1. I can see my datasets when creating a share, but can’t manage them via Datasets UI tab. I get the following error.

path_datasets2
path_datasets2968×480 7.34 KB

path_datasets
path_datasets450×934 19.7 KB

ElectricEel-24.10.1
Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz
RAIDZ2

Is there any command line commands I could use to change/fix this issue?

Any suggestions would be greatly appreciated.

I’m having the same issue. I guess i’ll just have to start over again with a fresh install. ugh

For what its worth, i was able to fix the issue by removing the partitions from my boot drive and reformatting it. I did all of this within the command line of the Truenas installer. I would assume you could keep all your datasets and settings using your backup of that data. I didn’t have a need to really save anything so i just deleted everything and started fresh.
I used Chat GPT to figure out the steps to remove the boot drive partitions. I believe this is where the unwanted data was being stored. Below are the commands i used.

Again, these commands were run while in the Truenas installer.

  1. Get list of drives
    lsblk

  2. Get into the (parted) interface, replace with the boot drive id from the list, eg: sdf
    parted /dev/<drive>

  3. Type print to view the partitions

  4. Type mklabel gpt to create a new GPT partition table, which will effectively erase all partitions

  5. Type quit to exit the (parted) interface. Note: i did not need to zero out the drive.

  6. I think i ran this as well but its possible i’m remembering incorrectly. This is supposed to remove any metadata from the drive if it was previously part of a ZFS pool, which it was lol.
    zpool labelclear -f /dev/<drive>

  7. Type exit to exit the shell

Continue with the installer.

No guarantee this will work for you but it did for me. I’m on a Dell R730XD server.

had the same exact issue doing an install (not upgrade) for 24.10.1 and restoring a 24.10.0.2 config. i just reinstalled 24.10.0.2 and it restored just fine. havent tried to upgrade, i dont think ill bother honestly.

Hi,
this one solved the problem for me!

tl;dr: ALWAYS save config with password seed before doing updates/upgrades or reinstalls - this way you can always upload the config fitting the (sub)version!

I had issues with my whole setup, so I ordered new SSDs as advised regarding Sata Controllers and cache - but could not migrate due to the System not really working.

Used a USB with the install image, installed the newest version to the new SSDs (boot-pool created in installation wizard), then bootet the system and uploaded the config. From there one mostly everything worked fine besides some problems i had due to bad setup on my side. Once I cleared all problems only the Datasets error occured.

I had an export with password seed from the previous version (24.10.1 I think), uploaded it and it worked just fine!

I am having the exact same ‘path’ error after a fresh install of 24.10.1 and restoring from a 24.10.0 backup

Is there any way to fix this? I would prefer not to install a previous version and reimport the old backup, since I made changes since then
