Issues creating SSD pool - slight drive mismatch

[ultraforce]

Hi just to note at the moment it seems like there is a problem with the pool creation in HexOS. I have a 256 GB and 250 GB drive and am trying to create a pool with it. However, HexOS is trying to create a 253 GB pool and then failing rather then a 250 GB pool.

Hi ultraforce,

I broke this comment out into its own thread as it's an issue with using HexOS vs meta talk about the FAQ.

In regard to the issue, I have to be honest, I'm not sure why that would happen! I'm sure others here might though, so I am looking forward to learning with everyone!

I also really don't know why it would happen. Just that it did.

I've now tried in truenas scale and got this error message

My experience is that TrueNAS, really, REALLY, does not like creating pools with different sized disks.  At least not straight out of the box.
