Trapped in /mnt/mnt after a improper pool import

Hello, I have just upgraded to scale 25, found VMs disabled by incus because my pool name contains space.
Searched for solutions, suggested: export pool, than import using cli with arguments.
After importing, datasets page seemes fine, pools page says no pool found. Consulted GPT, it suggested:


Then I found i am trapped in /mnt/mnt issue. Of course, rebooting or export-importing doesn’t help.

In this forum, I have found several threads relative to my case:

Tried this one:


Also tried

sudo zfs inherit mountpoint Pool_0

However, this pops up:

truenas_admin@truenas[~]$ sudo zfs set mountpoint=/mnt/Pool_0 Pool_0    
cannot unmount '/mnt/mnt/Pool_0': pool or dataset is busy

Again I consulted GPT, it recommends:

sudo lsof | grep /mnt/mnt/Pool_0
sudo fuser -vm /mnt/mnt/Pool_0

Here is where i am stuck. I have reconirmed all services apart from SSH is disabled;

This “kelnel mount” seemes important and maybe i shouldn’t mess with it.
Please help me to fix the mounting point, any advice are welcome, thanks in advance!

I do wish people would stop consulting ChatGPT and other dumb idiot AIs that simply parrot anything incorrect that anyone else has written!!!

We need to understand what your current pool status is in both Linux/ZFS and in the TrueNAS UI.

Please post screen shots of your UI Storage page (zoomed out so all pools are shown) and Datasets page with the tree collapsed to just the root entries.

Also post the results of the following commands each in its own </> box:

  • /sbin/zpool list
  • /sbin/zpool status -v
  • /sbin/zpool import

Once we have these we can decide what needs doing.

Thanks for replying!
Sorry for the annoyance caused by my idiocy :face_holding_back_tears:

Here is the screenshot of Storage and Datasets page:

Here is the result of those commands:

        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Thanks again for your help!

Thanks for the zfs list which was very useful.

You can try running the following commands:

  • sudo zfs inherit -r Pool_0

This should hopefully cause all datasets in the pool to inherit their mount points from the pool mountpoint. Once you have run this then run sudo zfs list Pool_0 again and see if the mount points have changed. If not then reboot and check again.

If after a reboot the mountpoints are still wrong, you can try:

  • sudo zfs set mountpoint=/mnt/Pool_0 Pool_0

which should change the root dataset location permanently and remount everything.

However, it seemes this command didnt work as expected…

Sizes are specified in bytes with standard units such as K, M, G, etc.

User-defined properties can be specified by using a name containing a colon (:).

The {user|group|project}[obj]{used|quota}@ properties must be appended with
a user|group|project specifier of one of these forms:
    POSIX name      (eg: "matt")
    POSIX id        (eg: "126829")
    SMB name@domain (eg: "matt@sun")
    SMB SID         (eg: "S-1-234-567-89")

D’oh. My mistake.

I have double checked the service and apps page:


Please tell me should I stop the middleware? or can i find the process using it and safely terminate them? Thanks!

Ah. Fortunately you got an error - because I had failed to consider that TrueNAS had some other datasets on here that have non standard mount-points. So apologies for me suggesting something stupid!!

Can you run /sbin/zfs list -r -o name,mountpoint,mounted Pool_0 and post the results so we can check whether anything was done?

And don’t reboot in the mean time.

Sure! Here is the output:

I have tried this fix from another thread:

First I made a checkpoint according to the walkthrough (better safe than sorry!)

truenas_admin@truenas[~]$ sudo zpool get checkpoint Pool_0
NAME    PROPERTY    VALUE    SOURCE
Pool_0  checkpoint  -        -
truenas_admin@truenas[~]$ sudo zpool checkpoint Pool_0
truenas_admin@truenas[~]$ sudo zpool status Pool_0 | grep checkpoint     
checkpoint: created Wed Jun 25 22:28:57 2025, consumes 1.38M

After unmounting (un-forceful), “zfs inherit -r mountpoint” seemes to work, at least partially.

truenas_admin@truenas[~]$ sudo zfs unmount Pool_0
truenas_admin@truenas[~]$ sudo zfs inherit -r mountpoint Pool_0
cannot unmount '/var/db/system': pool or dataset is busy
cannot unmount '/var/db/system/netdata': pool or dataset is busy
cannot unmount '/var/db/system/samba4': pool or dataset is busy

And “zfs get” looks right to me:

truenas_admin@truenas[~]$ sudo zfs get -t filesystem -r mountpoint Pool_0

However, as the other thread says exporting the pool via cli and import via gui to make changes permanent and let the middleware know, again i met with dataset busy.

truenas_admin@truenas[~]$ sudo zpool export Pool_0
cannot unmount '/var/db/system/samba4': pool or dataset is busy

The question is, should i forcefully unmount this dataset, and proceed with export-importing?
I have a checkpoint, but dunno whether the CoW mechanism can save me if i messed with this apparently system-related dataset.

Stop the SMB service. You can also reassign the “System Dataset” to the boot-pool temporarily.

That path in the error message lives on your System Dataset.

EDIT: Use the GUI to export.

When I am trying to help you - and especially after I have screwed up - please do NOT take your own actions. Mixing and matching actions from different solutions may screw things up completely.

We definitely need to fix a few things.

sudo zfs set -u mountpoint=/mnt/Pool_0 Pool_0

Then run:

  • sudo zfs list -r -o name,mountpoint,mounted Pool_0
  • sudo zfs get -t filesystem -r mountpoint Pool_0

and post the results.

Assuming that the zfs list shows mountpoints all corrected (i.e. as per the original list except “/mnt/mnt” is now just “/mnt”) then a reboot should bring everything back - but let me double check before you reboot.

Sorry for my haste :face_holding_back_tears:

I have run those zfs set -u, they didnt report errors.

But the mount points doesnt seemes fixed…

Thanks for replying!
SMB was already deactivated via gui.
For now, maybe I should not mix up solutions, but still let me thank you for your cordial help!

Still doesn’t look right. I ran some tests on my own system and because the zpool altroot is set to /mnt we need to omit that from the zfs set commands.

sudo zfs set -u mountpoint=/Pool_0 Pool_0
sudo zfs set -u mountpoint=/.ix-apps Pool_0/ix-apps

Then sudo zfs list Pool_0 again.

P.S. The @winnielinnie reply was posted in parallel with my own saying please don’t mix solutions - so I wasn’t referring to this when I said that.

Pool_0  15.0T  37.7T  3.25G  /mnt/Pool_0

Looking better, but sorry again I meant sudo zfs list -r Pool_0.

Hopefully it will look correct and we can do a reboot and see if it is all fixed.

EDIT: I have just noticed there’s some “none” in the mountpoint. Is that an issue for concern?

I think it is looking good. Worth a reboot and see if you can see the dataset contents and that e.g. apps are working.

Words just cannot convey my gratitude.
Reboot finished, the SMB sharing comes back up normal, as it did before.

Before jumping up from my chair to celebrate, please let me know is there additional steps to do, just in case?
