You are doing 'zpool create foo disk1 disk2 disk3'?

So the nexenta tool gives 2 different quantities, one is for the raw space, which is what you will see with volumes and the other is usable which is what you will see when you create folders. In 4.0 we are going to terminology that maps better to zfs terms of pools and datasets.

In the volume creation the size is the total of raw disk

Thank you everybody. Yes, that's how i was creating them 'zpool create foo disk1 disk2 disk3'

And yes, it was a big fake out. Because when i created the "folder" as Linda suggested... that showed the correct size. This concept of showing "raw disk" size of a raid is new to me, and i was confused. I was sure it was a stripe based on the size.

As somebody with a history with ZFS and an even longer history with RAID, i spent/wasted a bunch of time on this. So thanks for straightening me out. If version 4 shows a more representative size for the riadz, that would be welcome. I'm probably not the only one who got faked out. In fact, i talked to a big time Nexenta Guru who was just as confused as i was.

Now i can get away from hardware raid, because i know that prevents me from using all of Nexenta's Secret Sauce ( healing, no write-hole, caching, etc )

Thanks Everybody!!

I am confused now. When I typed my message, I meant to say 'zpool create pool raidz disk1 disk2 disk3', not 'zpool create pool disk1 disk2 disk3'. The former creates a 3-disk raidz1, the latter a non-redundant vdev. Are you saying you in fact did 'zpool create pool disk1 disk2 disk3' and therefore got a non-redundant pool?

While i have tried everything, i usually did it from the GUI ( once i realized that creating from CLI didn't help ).

I'd have to go back and pull my exact command, i just copied and pasted what you wrote thinking it was 'zpool create (name) disk1 disk2 disk3'
