I hope i put this in the correct category as there is no "Jails" category.
After the upgrade to Truenas Core i wanted to upgrade some of my iocage jails from 11.2 to 12.2.
For compatibility check i wanted to create a jail separate from production and test functionality.
i selected a name that was a few characters shorter than my production jail.
This gave me an error stating the jail already exists which is not true.
I replicated as follows:
- create a jail called abcdefg. this works fine.
- create a jail called abcd. this gives me an error stating the jail already exists.
I'm running the latest Truenas Core 12.0-RELEASE
i upgraded by exporting my config (11.x latest) , a fresh re-install and restore config.
