Use excess space on OS drive

[Soid]

Seems the installation did not partition the OS at all on installation. I happened to use a 1 TB NVME I had laying around, so it's pretty wasteful. I'd like to be able to at least use that excess space for caching. I was less bothered by it back when storage wasn't expensive, but now every bit matters. 

I installed way back when you first launched, so if you already changed this, let me know how I can fix it.

Unfortunately because of how TrueNAS is designed the boot drive cannot be used as part of a storage pool.

I don't imagine this will change anytime soon if ever.

Currently your options are
1) leave things how they are
2) get a new smaller drive 16gb-256gb and install hexos on to that and repurpose your 1tb ssd
3) <Advanced & unsupported use-case> install hexos on to a partitioned virtual drive via proxmox
