Hello, I have FreeBSD 7.0 and 4 250GB SATA disks and I would like to make one big 500GB 0+1 RAID array. My hardware is HP ProLiant ML110G5.
First I tried creating ATA RAID arrays with BIOS tools, but FreeBSD wouldn't recognize the arrays.
Than I decided to create the RAID-0 arrays with atacontrol. I succeeded, ending up with ar0 and ar1 each 500GB big. My plan was to install the FreeBSD as usual on ar0 and then add both into a gmirror array. However, I BootMgr seem not to be able to boot from RAID-0 array created with atacontrol? Is this correct? I guess this is because BootMgr knows nothing about striping and cannot read the kernel.
Finally I tried to create two slices on each drive. The plan was to join the first slice of all 4 drives into a gmirror array and mount it as / partition (I guess BootMgr would boot normally from such an array). Then I would merge the second slice of all 4 drives into a 0+1 array (first gstriping and then gmirroring them). I somehow succeeded this, but I also get a WARNING when booting the system:

GEOM_STRIPE: Device gs1 activated. WARNING: Expected rawoffset 0, found 63 GEOM_MIRROR: Device mirror/gm1 launched (1/2). GEOM_MIRROR: Device gm1: rebuilding provider stripe/gs1. Is this critical? It looks like the system is fine, though. Is there any "more proper" way to build such a system with RAID 0+1?
