Understanding Daily Run output

[Jdb]

I hope I'm just misreading this.

When I setup the test server I thought I created a RaidZ2 configuration with 4 2tb hard drives. When I am looking at the disk status it is referencing a ufs file system. I am guessing by the size that it is for the USB drive. Is that correct? (It's a 16gb usb drive but the numbers below do not add up to 16.)

Then in the status of zfs pools it is showing 7.25T of storage available. Since it's supposed to be a RaidZ2 should it be more around 3.85T in size?

Thanks,

Yes, the UFS file system you see is the OS on the USB stick.

The output of zpool list (which I believe is shown in the ZFS status section) needs some interpretation. I think it's actually just summing up the sizes of the child datasets, which results in the 7.x TB. If you want to get a better estimation, look at this line, which you should get with zfs list:

tank1 7.41T 1.14T 943M /mnt/tank1

Example of my pool, sum this up and you have your total space.

There has been some discussions in other threads how ZFS calculates the numbers, I can't recall the details at the moment. Maybe you have more luck by searching for those threads.

The size displayed by zpool list is actually very simple -- it's the raw size of all devices (not taking any redundancy into account).
2TB (power of 1000) = 1.819TB (power of 1024)
1.189 TB * 4 = 7,276TB
The displayed size of 7,25TB is slightly smaller than 7,276TB due to swap partitions and some other overhead.
