After updating to the latest version I am now having an issue where my boot pool is randomly getting filled up.
Nothing changed on my end from the previous release.

Where is your system dataset?
Try looking at this thread
In the end, that user did a config backup, overwrite install on boot device but you may find the issue by looking at disk usages in the CLI.

nvm found it
Ideally we woudln’t need to do that but if that’s the only solution I will 
You can still find out what is causing your boot-pool to fill up.
The du command-line tool is a good place to start.
Here’s an example that works in bash:
for dir in `ls -1 / | grep -v mnt` ; do du -hsx /$dir; done | sort -hr
You might need to run it with admin/root privileges, so that it can access and traverse all directories.
You can use sudo -i in SCALE to change into the root user. ( I think? I’m not sure what restrictions were put in place.)
It seems that for some reason it was writing apps to /mnt.
Now to find the random files it created
df -h | grep boot-pool

You can try booting into the previous boot environment and see if the apps location was changed.between those two. It is odd as it looks like you have been on 24.10.x series for a while, going by your screenshot.
It hasn’t changed yet. After restarting it seemed to stop doing it?
How should I proceed to clear these files?
This is a bit tricky.
The issue can occur if the ix-apps dataset fails to mount, and some of the apps system races it.
I’ve solved this by:
- deactivating apps, by unselecting the apps pool
- verifying that the ix-apps dataset is not mounted (
umount /mnt/.ix-apps) - then erasing the apps detritus. Using
rm -rf /mnt/.ix-apps(this is destructive, but the actual dataset should not be mounted) - re-activating apps by reselecting the apps pool

You’ll also have to delete the offending Boot Environment that is consuming 126 GiB.
Think it’d be better to boot to the previous install, unmount apps and delete the dataset then reinstall the update?
UPDATE: Rebooted into previous version and made sure all apps were functioning correctly. Then I deleted the new version and installed it again, everything went smooth this time

I have the same problem…
What is going on here? i cant remove mnt/.ix-apps because it has important data.
You have at least one application misconfiguration and its storing its data on the boot pool / in the apps location.
You’re not supposed to. Reboot to the previous install and do as I said. Set the previous install as the active/primary and then delete the new version once you verify that your apps work
Probably not. In my case I had changed literally nothing and after updating it had not mounted the apps pool properly. Please don’t assume otherwise
I found the issue. It indeed was a misconfigured container. I just need to figure out why it saved data (backup data) into my /root/docker/ path.
All this TrueNas Host-Path thing and different mount paths giving me a headache >.<

Hey guys in this topic, I have the same prob lem and now I cant boot into the system to show the control pannel. Only have a bash to operate. What can I do now to solve it? T^T
See Boot-Pool 100% Usage? - #6 by winnielinnie
That should at least let you find what filled up
