SOLVED Reconstruct iocage

[mattx38]

Hello,

I recently built my NAS with TrueNAS Core installed on it.
It works perfectly for 2 weeks now.
I installed Plex to browse my personal videos over my LAN and it's ok. I wanted to install NextCloud to backup photos from my phones, ok...

So I began to install NextCloud but during the installation, I reloaded the web GUI and it crashed the installation.
I relaunched the installation, but it says there was already the jail installed, so I deleted the "nextcloud" dataset into the socage dataset ; I know now it was not a good idea.
Now when I try to install it again, it says that there is a missing configuration.

As I want a clean installation of the NAS, my question is to know if I can delete the whole socage dataset ?
The idea is to restart from scratch for the jails. If I do well understand how it works, when I will ask to install a new plugin, the system will recreate the iocage. Is that correct ? I read here that the command "iocage clean -a" should destroy all created iocage data. Can I securely do it ?

As I did a first mistake, I prefer now to ask you before doing anything else.
Thank you.

Hello.
I respond to myself, if it can help others.
I passed the « iocage clean -a » command then I deleted the iocage dataset from my pool.
At the first plug-in install, TrueNAS asked me where to install iocage, I specified the only pool I have and it’s back, clean and functional.
