Update Error: [EFAULT] 'Insufficent space to install update' (updating 12.0-U2 to 12.0-U3)

[nbinding]

Hi Guys,

I am fairly new to TrueNAS - having some trouble with the update process.

I have checked a few suggestions on deleting and creating a new boot environment, and checking that my boot disk is large enough etc.

I am currently using a spare NVME 256GB SSD as my install media, and should have plenty of spare space.

When I run the automated update, I get an error stating: Error: [EFAULT] 'Insufficent space to install update'

The update if it helps:

Upgradebase-os-12.0-U2.1-b961209e0a49042f51315f620cc29e9d -> base-os-12.0-U3-48792992232e151e13f1e0bb4c3f9493Upgradefreebsd-pkgdb-12.0-U2.1-b961209e0a49042f51315f620cc29e9d -> freebsd-pkgdb-12.0-U3-48792992232e151e13f1e0bb4c3f9493Upgradefreenas-pkg-tools-12.0-U2.1-b961209e0a49042f51315f620cc29e9d -> freenas-pkg-tools-12.0-U3-48792992232e151e13f1e0bb4c3f9493

Please let me know any other information that might help with troubleshooting.

I have since located the issue, my root mount had a folder mounted to it, taking up 99% of the space, I have since purged this and can confirm boot disk space restored.
