On the controller there it says that it supports freebsd 6.1. And yes there
is documentation on how to install freebsd 6.1 on the raid.
But for now i have installed freebsd on a RAID1 system, and i have problem
getting the card detcted, i run a 5TB RAID 6 on this card.
Didn't thought that it could be that much differens between version 6.1 and
6.2. Gonna try to reinstall. After the reinstall i got the card up and
running. I see it get detected and it all looks ok. I go in and do a fdisk
on the drive and label/mount it. I do all this in sysinstall.
I can see that the drive is 4648GB so it all looks ok with the RAID 6 Drive.
When i later quit sysinstall and check the mounts i see that the drive space
is 532GB and available space is 500GB. This looks totally wrong. Is there
any limitations that im not aware of?
