Select bigger NVME Boot Disk for apps?

[doe24]

hello, should I choose for boot disk a bigger size like 250gb for maybe some plugins, apps? are these installed on os disk or on data pool?

If you want to use the GUI to manage things and you want support, you'll need to separate your boot pool on one (or more) drive(s).

Jails, VMs or anything else lives in a data pool.

Doing what you ask isn't supported on TrueNAS.

It is supported on a version forked from FreeNAS long ago (now called XigmaNAS), which is much harder to learn and has very different levels of documentation and forum support.
