Hi,
I have been trying to test a few options for a home NAS, and i was thinking of setting up freenas.
I have been testing this on a virtual environment before going to spend large amounts of money in hardware, and have been surprised how good freenas is.
That being said... i have a big problem:
I created 6 2gb disks (virtualdisks but is for testing only so makes no difference), and created a raidz volume with 5 of them.
At this point i expected to get a volume with 8gb (4x2gb data +1 parity), but the volume was only 4gb. I ignored this and thought i had messed up somewhere, so i created it again and had the same behavior.
so i deleted the disks one by one and replaced them with 5gb disks (so i could test if the volume would magically grow when all disks were substituted) and it grew, but again to half the expected volume size.
I deleted the volume and when i come to recreate the volume i get:
5x1x5.4 GB
Capacity: 12.00 GiB
a single disk as stripe shows:
1x1x5.4 GB
Capacity: 3.00 GiB
On the first case i expected 5*5.4 (raidz) to be capacity 20gb
On the second one i expected the full 5gb to show as capacity.
There might be a very obvious reason for this but i cant think of one. I googled and looked through the forums for hours and came up with no explanation for this.
This is the only think preventing me from going to buy the hardware for this... if i lose more than half of the disks capacity it's not a good solution for me.
Thank you in advance for your answers.
