Raidz displays incorrect size

So I just tried what somebody here suggested and set up my backupserver with a zraid2 over 16 disks (4x4 groups)

zpool create tank raidz2 c7t0d0 c7t1d0 and so on.

zpool list showed a correct info about 5,4T in size (I did not use all disks), but when I did a df -h, it showed me only half the size? Then I created a file with mkfile 10G test and it showed up with ls -lh as 10G. But looking at df -h again it showed merely 1.0G used? Odd...

My gosh, I just added the remaining four drives to the pool with zpool add tank raidz2 c7t12d0 c7t13d0 c7t14d0 c7t15d0

It worked, but suddenly the machine died under my fingers, so to speak! My gosh, could somebody please tell me it did not crash because of a single broken disk or something like this? At the moment it responds to ping, but no ssh access.

My god, can somebody please tell em, this is a happy little accident, nothing about zfs crashing from time to time? I have spent the last two months talking colleagues and boss into Solaris and zfs, bought hardware worth 2k+ and if it's all screwed up now, I have to look for a new job, it seems...

F***!

Well I tried an installation on a USB-stick, maybe that's the problem. It showed some strange behaviour, like it crashes when I boot off the USB-stick as a first boot-device. But when I move the cd-rom as the first boot-device and the stick as second, it boots just fine.
