I have a pool of SSD's called in an imaginative manner SSDPool.
It consists of 6 SSD's in 3 mirrored vdev's and an Intel Optane slog
Its purpose in life is to work as iSCSI storage only
Note that sizes are approximated for ease of writing
Each disk is 1TB so the raw storage capacity is approx 6TB
Given that its mirrored pairs then the raw capacity is 3TB
The iSCSI zvol itself is 2.17 TiB of 2.47 TiB available so in round terms I have about 2TB of available space from 6TB of raw disk (although 3TB might be fairer). Creating the zvol would only let me use 80% (and I may not have used quite all of that)
I am only using 450 GiB of the 2TB - so I do have easily enough space. It just doesn't seem very efficient
